Hi All,

I am looking to set up an email server (on my existing home server).

Any recommendations? I want the basic abilities (smtp imap and pop / mail groups / address books etc.) It will mainly be used with my wordpress / osticket installs as well as forwarding emails to lists.

I have not set up a linux mail server before so would not know where to start. The server is opensuse 42.1 64-bit

Thanks

Dovecot is a good bet. It supports IMAPS. SMTP is a different issue and address books are a function of the email client. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I have found this guide (for 13.x but should work on 42.1)

It sort of makes sense but I cannot work out, how do I set up the mail server for multiple domains? I have several websites hosted and each one needs to have its own mail.domain.com and me@domin.com for example.

It is the one server with one IP address.

I am doing same with Sendmail + Spamassassin + Cyrus Imap together with Horde for a web interface. -- --Moby -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

so far:

I have installed postfix and postifx admin. I have followed the guide here http://www.linuxmail.info/multiple-domains-postfix-admin-centos-5/

and set up postfix. (not dovecot yet)

How can I test postfix?

I am also a bit confused, I have added my email addresses in postfix admin. Do I also have to make local users with the same name and password?

I do not know what is "postfix admin". And no, you do not define users with postfix anywhere. After installing postfix (which is already done on an openSUSE system by default), without doing anything else, you can test that it works by sending email from one local user to another local user. That's it. Sending email to outside, or receiving it, depends on whether you have a fixed Internet IP, and a proper domain. If you don't, it is others who have to send and receive emails on your behalf (say, gmail). Your role is simply to hand your email to them, and picking the answers. Really sending email yourself is difficult because of antispam protections by others. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

The Postfix documentation descried a number of ways that you can authenticate users in Postfix, but why should you? You need to have a clear understanding of what constitutes a user. Until you understand that then yes, you are going to be confused. Again, Dovecot has a number of ways to authenticate the user. Both have a default of making use of the users that have an account on the machine, that is, that they are in /etc/password. That is NOT a good way to set up an ISP! You don't want people to have access to or accounts on the main machine just to process email. You may also be faced with the issue of having multiple machines and even different ones for user to send email (Postfix) and read email (Dovecot). Both have facilities to use some other kind of authentication service, be it NIX/YP, shared files via NFS, or, perhaps more sensibly, an authentication server, be it Kerberos or Radius. Again the documentation for doing this with both Postfix and Dovecot is extensive. My experience is that many 'nationwide' ISPs that serve though regional points-of-presence (PoP) make use of Radius or something similar, since that can be backed with a distributed database such as LDAP. it's easy to find examples and how-tos for all this with Google The differences between openSuse and Ubuntu are actually about the difference between zypper and app-get, nothing to do with Dovecot or Postfix. https://www.howtoforge.com/the-perfect-server-opensuse-13.1-with-apache2-mys...

I think you will discover there is even more for a Linux mailserver. I frequently deal with MS Exchange admins who cannot answer simple questions. For instance, what are the exact criteria for an email ending up in the Junk folder?

How can I test postfix?

Postfix has three purpose - receive mail, delivery locally or pass on to somebody else (e.g. dovecot). Which one do you want to start with?

I found this: https://www.exratione.com/2014/05/a-mailserver-on-ubuntu-1404-postfix-doveco...

but still no luck. I followed it exactly (changing usernames and passwords and file paths accordingly) but I cannot get postfix to start up at all. There are no errors logged in systemctl, just blank.

I even went back to default postfix file and it wont start.

How did you determine that it wasn't running and what error msg's were provided?

Are there any working tutorials? I basically just want a smtp imap pop3 server using postfix dovecot and roundcube all using virtual users in sql. This needs to work for multiple domains.

This seems very overly complicated on linux. MS exchange 2013 took me an hour to set up at work.

Has anyone managed to configure such a setup (or similar) that is working that could provide me with some configuration files to go on?

hello paul, for my postfix setup with multiple domains, virtual users, imap/s,pop3/s ... i'm using dbmail since many, many years without big problems or whatsoever. http://dbmail.org/ perhaps this might help in finding a solution with postfix and virtual domains / users? greetings becki -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

For someone with little or no experience in postfix, dovecot etc., that is a pretty tall order. It's entirely doable, just not in 5 minutes.

Starting from scratch, it would probably take me a day to get it working and tested on Linux and perhaps until Christmas on MSEX2013 :-)

Yes, my mailhost is pretty much what you're asking for. Mail-users and domains are stored in mysql and accessed via pam/nss. Mails are received by postfix, handed to dovecot with lmtp. roundcube runs on a separate webserver. The only slightly tricky bit here is getting your system to access user credentials in mysql, because you need to do that manually. The rest is almost out-of-the-box when you install openSUSE. 1) postfix - just install and start. It needs to be configured for - receiving external mail. External IP, reverse DNS mapping, define virtual domains. (virtual_mailbox_domains). Maybe also TLS. - mails for local delivery to be handed to dovecot. (virtual_transport) 2) dovecot - configuration needed: tls, quotas, sieve, indexing. This a little more involved. 3) roundcube+apache. Nothing much to it, it's a plain PHP app on apache. 4) mysql - database setup, maybe adapt your schemas to fit your needs. pam+nss setup. First of all, you need to get postfix to run. It is pretty odd that it won't start in the default setup, you need to investigate that first. The normal postfix setup starts just fine, but only handles local mail. If that doesn't work for you, something went wrong.

Thanks. I just tested another 42.1 box and postfix is indeed working by default. Maybe my tinkering has broken it. Although I only changed what the how-to said that I sent previously. How can I re-set postfix and dovecot to default on the mail server? Do I just simply uninstall the package and reinstall? On 2 July 2016 at 08:57, Per Jessen wrote:

Using a howto for Ubuntu... Don't. When you use a howto for another distribution, you have to be aware of the differences.

How can I re-set postfix and dovecot to default on the mail server? Do I just simply uninstall the package and reinstall?

That might do it, but probably you also need to delete the configuration files in between. Contrary to Windows, reinstalling a program does not alter the configuration files in Linux. Or, you might copy those configuration files across from the working machine. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

Hi All, Hopefully I will have some time over christmas to have another look at my mail server set up. Thanks for all the advice so far, will try out suggestions soon. Next step: I already use owncloud and have several users all utilising documents / calendar and contacts. So I would like to integrate my mail (postfix and dovecot) into this. (owncloud has a roundcube plugin and we all use thunderbird on our PCs). One thing I would like to be able to do is authenticate my MDA (dovecot) against the owncloud users table. Has anyone done such a thing before? I have read you can set up dovecot to use SQL user tables so perhaps I could access the oc_users and oc_groups tables directly? But I have no idea how ownCloud encrypts the passwords. Thanks Paul -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
