You said Sendmail, but SuSe uses Postfix (at least on my machine using 10.1). A really nice graphical interface for configuring most things is Webmin : http://www.webmin.com/index.html Mike pipiriz wrote:

Both are supported.
I realize that both are supported, but Postfix is installed by default. Mike -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I always advocate Postfix as the better alternative, but Carlos is right. This isn't helping the OP. Perhaps the OP should try to use the MTA configuration module in yast.

Actually I hate Postfix and have used Sendmail for over 15 years. What I was trying to say was that maybe he has them confused. I did send the OP a direct reply (forgot reply to was not set to list) telling him make changes to sendmail. I now think it is time to drop this part as it is not helping anybody. Mike

One of the best places to information about sendmail is to go to: http://sendmail.org/ To setup DNS for private address space, you can find at: http://sendmail.org/tips/private-dns/ Of course private address space was never mentioned, I'm just assuming that he does not have valid IP and that all internal IP addresses are being NAT'd to a valid IP address on the internet.

I was also hoping for a bit more specific advice. For Postfix the procedure would be: servername: www domain: example.com as root: postconf -e "myhostname = www.example.com" postfix reload If you've got some strange setup where you don't want to use the hostname as HELO, you can set the helo name of the server with: postconf -e "smtp_helo_name = mail.example.com" postfix reload The default of smtp_helo_name is $myhostname: # postconf -d smtp_helo_name smtp_helo_name = $myhostname So usually it's not neccessary. I tried to find the information on the sendmail.org site, but didn't find anything useful within a few minutes. Do you have a more specific link for basic Sendmail setup including hostname?

Judging from the hostname "www" that he used he is probably trying to send mail from a webserver using the local Sendmail installation. So he probably has an official IP (and hopefully correctly set up dns and reverse dns). Sandy -- List replies only please!

Yes, that's right. We told him (in the Spanish list) to check using <http://www.dnsreport.com/tools/dnsreport.ch?domain=tudominio.es>. He had a problem with the reverse dns and said later that had spoken with his ISP and solved that. So that side should be correct.

hi, John, this is the solution: i found the answer to my problem in the configuration file sendmail.cf
# my official domain name
# ... define this only if sendmail cannot automatically determine your domain #Dj$w.Foo.COMUncomment the macro and include the fully qualified host name.
The entry is similar to this for penguin.southpole.com:
i use:
Djwww.mydomain.com
restart the sendmail and that´s all.
this solved the problem.
thanks to all
hanks to the list
btw

Since I don't use any mailer at home, I have removed postfix and have installed sendmail. This will allow me to see how suse uses sendmail (or modified from original), will also set it up to use my ISP smtp server as a smart host. Nobody will be able tell you what you need to do as each site is different. But at least I will have a better idea of what you need to do. Mike Sandy Drobic wrote:

Please post the neccessary steps to set the FQDN hostname in Sendmail, so other people will be able to find the solution in the archives. There are much less people using Sendmail here than people using Postfix, so it's not easy to get help for Sendmail here. The steps I mentioned to configure Postfix will work on any system, by the way, regardless which distribution you use.

So the output of `hostname -f` is used as the FQDN by sendmail? Well, that should be enough to get the original poster on the right track.

No, I don't think so.

I believe that Yast would set that correctly; alternatively, you can edit /etc/sysconfig/sendmail and run SuSEconfig afterwards. I did that when sendmail was the default in SuSE and it worked fine without having to touch the real sendmail configuration. But I don't remember the details. With postfix, we can let Yast do an initial configuration, then forget Yast and do it ourselves: the config is humanly readable ;-) However, I'm not going to install sendmail to check. But looking inside the rpm, I see there is a '/sbin/conf.d/SuSEconfig.sendmail' file. Let's see what I can learn.

Only the problem was a bad configuration in the sendmail.cf file. This is the change I was made in this file. thanks again.
thanks Sandy, in the page
i found the answer to my problem in the configuration file sendmail.cf
# my official domain name
# ... define this only if sendmail cannot automatically determine your domain #Dj$w.Foo.COMUncomment the macro and include the fully qualified host name.
The entry is similar to this for penguin.southpole.com:
i use:
Djwww.mydomain.com
restart the sendmail and that´s all.
this solved the problem.
thanks to all
hanks to the list
btw

Sorry. It was "www.dominio.com", which is our way of saying "www.somedomain.com". I don't know his real domain, but he said it was correct, and I think he is right in that (he is receiving email, I understand, so he must have an MX entry).

Don't touch sendmail.cf nor submit.cf but use the configuration with /etc/sysconfig/mail and /etc/sysconfig/sendmail togther with `SuSEconfig --module sendmail' _OR_ disable SuSEconfig within /etc/sysconfig/suseconfig if you're doing all by hand (without using YaST and/or SuSEconfig anymore). If you're are touching files like sendmail.cf SuSEconfig will not touch such file anymore due MD% checksum comparision. And even if you change sendmail.cf and/or submit.cf for you're own you should use /etc/mail/linux.mc and/or /etc/mail/linux.submit.mc as starting point to use the M4 macros for generating sendmail.cf and/or submit.cf ... simply to be sure not to run over a removed TAB with space within a .cf file :)) Werner -- "Having a smoking section in a restaurant is like having a peeing section in a swimming pool." -- Edward Burr -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Glad to hear that your problem is solved. Just to clarify a few general things about SMTP: - the HELO string that the sending server is using is not derived from DNS, it's usually the hostname that is configured locally on the machine. RFC 2821 says, this string has to be a resolvable FQDN for a domain/host. - a sending server does not neccessarily need a MX record, only correct A record and reverse DNS - the MX record is used to announce servers that will accept mail for a domain, not neccessarily server that will send for a domain. - if the server is both sending and receiving mails for a domain, then all records (MX, A, reverse DNS) are neccessary. - if no MX record is set for a domain, mail will be sent to the A record of that domain. Though you should set a MX record. Sandy -- List replies only please!

Fortunately (for me) not many enforce this.

Unless some one enforces it on the receiving end as an antispam measure, I guess :-?

A lot of host do not have correct HELO implemented, Postfix can check this with REJECT_UNKNOWN_HOSTNAME (for Postfix 2.3+ this has been renamed to REJECT_UNKNOWN_HELO_HOSTNAME). Even big Internet companies like Yahoo and Google have misconfigured HELO for their servers, so it's not recommended to use these restrictions on a general mailserver. Postfix doesn't even have a check that says the a record and helo must be identical, and for good reason. To number of false positives would be astronomical. (^-^) It is considered "best practise", but it's not what is implemented on many servers.
- a sending server does not neccessarily need a MX record, only correct A record and reverse DNS
Unless some one enforces it on the receiving end as an antispam measure, I guess :-?
Then he's an idiot. Especially big companies that are sending millions of mails per day have dedicated send-only mailservers, so it's NOT a good idea to demand that the very same server that is sending a mail is required to accept mail back for the sender address.

I encountered such a weird "antispam" measure only once. This is not covered by any RFC. RFC 2821 explicitely says, if no mx record exists for the recipient domain then the server has to resolve the a record of the recipient domain and deliver the mail to that server.

I installed sendmail and have sent myself email messages which went to my ISP first. Suse has done a great job in using Sysconfig Editor via yast, just choose network - mail - sendmail. This is where I set the SENDMAIL_SMARTHOST to point to my ISP smtp server. Modified the /etc/mail/aliases file to send root and my mail to my ISP (don't want to keep it on the machine).

Actually I hate Postfix and have used Sendmail for over 15 years. What I was trying to say was that maybe he has them confused. I did send the OP a direct reply (forgot reply to was not set to list) telling him make changes to sendmail. Could you post those changes here, just for the record? Even if I don't use sendmail now, I like to learn. :-)
One of the best places to information about sendmail is to go to: http://sendmail.org/
I was also hoping for a bit more specific advice. For Postfix the procedure would be:
servername: www domain: example.com
as root: postconf -e "myhostname = www.example.com" postfix reload
If you've got some strange setup where you don't want to use the hostname as HELO, you can set the helo name of the server with:
postconf -e "smtp_helo_name = mail.example.com" postfix reload
The default of smtp_helo_name is $myhostname: # postconf -d smtp_helo_name smtp_helo_name = $myhostname
So usually it's not neccessary.
I tried to find the information on the sendmail.org site, but didn't find anything useful within a few minutes. Do you have a more specific link for basic Sendmail setup including hostname?
To setup DNS for private address space, you can find at: http://sendmail.org/tips/private-dns/
Of course private address space was never mentioned, I'm just assuming that he does not have valid IP and that all internal IP addresses are being NAT'd to a valid IP address on the internet.
Judging from the hostname "www" that he used he is probably trying to send mail from a webserver using the local Sendmail installation. So he probably has an official IP (and hopefully correctly set up dns and reverse dns).

Glad to hear that Suse did a good job. The poster with the original problem wasn't using a smarthost, he wanted to send directly, otherwise he wouldn't have run into that much trouble.

Guess: This because the DNS of the network isn't configured or not configured in the correct way. First of all the system requires a name (normally without any domain name part). Then the system requires for each network a Full Qualified Domain Name (please note that the former name can be part of the FQDN but can also an other host name and can also be different for each network). At last the YP domain name has nothing todo with the DNS domain name even if normally identical for practial reasons. If postfix or sendmail do not know about the FQDN of the networks accessible then it have to be configured. This can be done by using a DNS server of the appropiate network or within the configuration of postfix or sendmail.

If your machine's name is set up properly in yast it will pick this up automatically. You can over ride it in /etc/sendmail.cf by finding this section and setting it as needed... # who I masquerade as (null for no masquerading) (see also $=M) DMYourDomain.com The less you do inside of sendmail.cf the better. So make sure you machine name settings in yast are correct first, and then carefully follow thru the sendmail settings in Yast MTA settings. -- _____________________________________ John Andersen

Looks more like your MUA can't figure out the FQDN. See if - /etc/HOSTNAME contains the FQDN - OR - - /etc/HOSTNAME contains the hostname and /etc/domainname contains the domain name part, both together forming the FQDN
