General :: Setup A Functioning Imap And Pop3 Mail Server Using Dovecot-postfix?

May 4, 2010

I'm somewhat familiar with Linux and became pretty decent at installing and configuring packages in Ubuntu. One of the things I was able to do with my tinkering was set up a functioning imap and pop3 mail server using dovecot-postfix. Now I'm experimenting with Slackware to get the feel of another distro, and I noticed that the mail server packages were already installed. On my client computer they can pick up that I have users configured and my mx record is working.

However it is failing to send mail saying that it is failing to relay the e-mail message and that the server responded 5.7.1 which was a problem that I was having in Ubuntu when first configuring the mail server. The fix was to edit the postfix.conf file and adding the localhost name of my server. Does anybody know of the file that I need to edit to make it possible to relay my messages with both pop3 and imap.

Ubuntu Servers :: Postfix Configuration - Send Mail To Other Domains

Nov 5, 2010

Let me start off by saying I am experienced with computers, though my knowledge of Linux and networking is limited. I've just recently started setting up a Ubuntu 10.04 server to be a SMTP server. I've followed this guide by the letter: [URL] What I've attempted, to test the server, is the following:

telnet localhost 25
ehlo localhost

(this returns all the desired information) I then do a MAIL FROM my domain which is accepted, and try to do a RCPT TO an external mail server (gmail) to test sending an email. I am then told 'Relay Access Denied'. I'm sure that there's something fundamental that I'm either not understanding or not doing correctly. I simply want an SMTP server that can send to other domains. What do I need to do?

Ubuntu Servers :: Send Mail Doesn't Postfix SASL Work

Nov 27, 2010

I'm running a server with Ubuntu 10.04 and I have installed postfix and courier. The server can recieve mail and I can fetch them using POP, but when I try to send mail it doesn't work. Postfix itself can send email if i telnet from localhost and I am using my ISP as a relay because they block port 25. I'm using outlook 2007 on my client computer and it just says that the server rejects the login attempt and tells me to check my username and password. Postfix listens on port 12 as well because the client connection also has outgoing on port 25 blocked. I have tried to use telnet to connect to the server, and I can connect. This is what I get:

[Code]....

Now what? I've tried searching for the answer but all I can come up with is AUTH PLAIN or AUTH LOGIN, but I don't know what to type after that.
