After 16 long hours I've finally fought through and made a E-Mail server. Still have some rough finishes, and some problems, I can't figure out on my own. So, as a first post, I must ask for help. Here is my configuration for Dovecot :: main.cf # BASIC CONFIGURATION myhostname = mail.domain.cf mydomain = domain.cf myorigin = $mydomain mydestination = mail.domain.cf, domain.cf, localhost relayhost = mynetworks = 127.0.0.0/8 Everything works fine - but not that mydomain string. It just wouldn't do and convert it like a proper string should do. I tried changing origin, removing mydestination and all other possible things my imagination can do. Still, using mail function and sending to my personal e-mail address will result in this: Return-path: Envelope-to: roberts@mysite.lv Delivery-date: Fri, 02 May 2014 21:05:08 -0500 Received: from [188.226.228.103] (port=36029 helo=mail.domain.cf) by somehosting.lv with esmtp (Exim 4.82) (envelope-from ) id 1WgPK8-0004Lx-4J for roberts@mysite.lv; Fri, 02 May 2014 21:05:08 -0500 Received: by mail.domain.cf (Postfix, from userid 1002) id 3D3BE1231B8; Fri, 2 May 2014 22:05:07 -0400 (EDT) To: Subject: Hey, what's up? X-Mailer: mail (GNU Mailutils 2.99.98) Message-Id: <20140503020507.3D3BE1231B8@mail.domain.cf> Date: Fri, 2 May 2014 22:05:07 -0400 (EDT) From: roberts@localhost.domain.cf (Roberts) -- I've tried some relays - but then it just didn't send. I'm not actually caring as much for how it looks - but that's my server, and I'm trying to integrate RainLoop on top of it. Managed to finally get a connection - but I can't sign in using non-root user with simpleguy@domain.cf localhost dovecot: auth-worker(2098): Error: pam(simpleguy@domain.cf,188.226.xxx.xxx): pam_authenticate() failed: Authentication failure (/etc/pam.d/imap missing?) localhost dovecot: imap-login: Disconnected (auth failed, 1 attempts in 5 secs): user=, method=PLAIN, rip=188.226.xxx.xxx, lip=188.226.xxx.xx$ It's same for Thunderbird. Can't log-in. Not sure why. Would be greatly appreciated, if you could help me deal with this problem, as well as giving tips for the second one (disconnects). I DID learn a lot today already. Here's the additional info, if you are looking to help me: From what I gathered, there is something limiting SSH/SSL connections.
