Okay, asuming you have the following, linux.mydomain.com - box you're on mail.mydomain.com - your smtp server user@mydomain.com - who you want to send to in /etc/sendmail.cw you should only have the single line linux.mydomain.com in /etc/sendmail.cf you should add the line DSmail.mydomain.com (there is probalbly already a DS line in but commented out, just edit that one) The only DNS entry you need is a 'A' record for mail.mydomain.com. If from the linux box, you can 'ping mail.mydomain.com' then your DNS is set up enough. Once you've done this, then mailing to user@mydomain.com should work.

Thanks Gary Ive been using sendmail to mail a user with an account on my SMTP server. The user does not have a password on my LINUX box, mail to users on the same host works ok. Should i need aliuses for all users or passwords for all users on my LINUX box, i hope not. Do i need to customise my sendmail.cf file more?Should i use my ISPs DNS domain in my sendmail.cw file? Does this smarthost line still sound possible? The DNS server is working better now i took the server host name of the MX record (NT Optional field) and points to the ISP's DNS with the relevent MX config.
Getting there but so near but so far!

Thanks for your prompt reply! I have my domain entry in my sendmail.cw file however, and i havent even started testing the cgi script at the moment, im just testing sendmail. If i email (form the root user) an internal address, the address comes up with the message "user not known". Sendmail to an
What do you mean by internal address? on the same host, or on your network? This sounds like the user you're sending to doesn't exist and doesn't have an alias entry.

uninterestingly!) an nslookup on my domins mx record just brings up my pdc ip address, if i lookup my pdc.domainname i get all the mx record info. Lookups on remote DNS including my ISP's all seem ok. Before my bash prompt i have "root@LinuxSrv" should this be "root@domain name" to work. I suspect my DNS config or my sendmail config now.
Is this box your main mail relay, or are you using this to send mail only from this host? If you have another mail server, did you try setting the smarthost line.
Sorry to go on but i need this sorted! The idea behind it all is to use "Hot Potatoes" a free (to Schools, check it out! www.halfbakedsoftware.com ) windows package that can produce interactive media web forms and can email results to the teacher.
If you could give us some more details about your network topology we may be able to provice more info.

firstly, it will not have anything to do with Samba. Mail (SMTP), is a purely IP based protocol and does not interact with Samba.
What you need to do is find out if the problem is with the CGI, or with sendmail. The easiest way to do this is to log in using telnet/ssh etc. and try sending a message using mail. Next, try sending a message using sendmail, by emulating the cgi (probably by feeding a message to sendmail using the '-t' and maybe even the '-f
' parameters. Finally, re-test your cgi and then look at the apache and sendmail logs. If all else fails, (and asuming you're using perl), try the Mail::Sender module available from CPAN. It completely bypasses sendmail and send the message itself.
Having said that, it probably is your sendmail config that is the problem. You probably haven't told sendmail how to handle mail not for the host it's on.
If you want sendmail to handle mail for other domains besides the one it's on, then you need to add them to the /etc/sendmail.cw. For instance if you want it to handle network.co.uk as well as host.network.co.uk you need to add network.co.uk to the file.
Alternatively, add a 'DS' line to /etc/sendmail.cf. e.g.
DSmail.network.co.uk
This tells sendmail to send all mail not destined for itself (sendmail.cw) to a Smart host who will then forward the message to the destination.
