Hi! I'm trying to setup Postfix+Courier on my CentOS 5.5 server with the howto: http://howtoforge.com/virtual-users-and-domains-postfix-courier-mysql-centos5.1 I connect to pop3 (telnet localhost pop3) and it works fine but when I type the command "telnet localhost 25" i can see something like: Trying 127.0.0.1... Connected to localhost.localdomain (127.0.0.1). Escape character is '^]'. Then the only thing I can do is to close the console. I tried to type ehlo localhost without result and also tried quit, with the same (no) result. I hope you could help me. Sorry about my (limited) english :S
You are connected to your SMTP Server over telnet, you can now test the server you have to send commandos to him for this. For example type: EHLO yourdomain.com When you do AUTH LOGIN you could even do a login and send a mail over it. Abit descriped here: http://technet.microsoft.com/en-us/library/aa995718(EXCHG.65).aspx
Thanks for your reply. I typed EHLO mydomain.net, EHLO server.mydomain.net, EHLO localhost, AUTH LOGIN... and nothing happens. I also tried: o myserver.mydomain.net on telnet prompt and this is what I could see: telnet: connect to address 172.16.xxx.xxx: Connection refused telnet: Unable to connect to remote host: Connection refused The smtp is listening and both iptables and selinux ar off..what can I do? Thanks
Strange is that with quit you dont get a '221 Bye'. Sounds like a faulty postfix, probably something gone wrong when recompiling it with quota ... just a thought.
Hey! It's me again. I solved the problem. Well, not exactly... I have to say that I don't know which the problem was, I restarted the howto, recompiled postfix, etc.. and now it works... But I have another problem: I tried to install squirrelmail with the howto http://www.howtoforge.com/virtual-u...urier-mysql-squirrelmail-centos-5.3-x86_64-p5 and when I type the username and password and press login in Squirrelmail an error appears ERROR: Connection dropped by IMAP server. In the maillog I see: Code: Feb 2 20:55:29 [I]server[/I] imapd: Connection, ip=[::ffff:127.0.0.1] Feb 2 20:55:29 [I]server[/I] imapd: LOGIN FAILED, [email protected], ip=[::ffff:127.0.0.1] Feb 2 20:55:29 [I]server[/I] imapd: authentication error: Input/output error I've installed Thunderbird and fails too. Any suggestion?
I've created a new user (user1) and the error persists... Maybe I have to recompile courier packages too.. Edit: Nothing. I've recompiled courier packages, with more recent versions, but it still doesn't work. I've tried to send an email with telnet connection..and this is what I could see: 220 server.mydomain.net ESMTP Postfix auth login 334 VXNlcm5hbWU6 base64_username 334 UGFzc3dvcmQ6 base64_pwd 535 5.7.0 Error: authentication failed: generic failure maillog: Feb 3 17:52:07 server postfix/smtpd[24194]: connect from localhost.localdomain[127.0.0.1] Feb 3 17:53:04 server postfix/smtpd[24194]: warning: SASL authentication failure: could not verify password Feb 3 17:53:04 server postfix/smtpd[24194]: warning: localhost.localdomain[127.0.0.1]: SASL LOGIN authentication failed: generic failure
I've tried to send an email between two same-domain users trought telnet and without AUTH LOGIN and it works. Seems to be a problem with sasl authentication. Is there an easy method to disable it and check Squirrelmail, Thunderbird..etc..? What could be wrong? Thanks for your answers
First, make sure you authenticate with full email addresses, not just with the local part (the part in front of @). Also, please make sure that the local part does not exist as a system user in /etc/passwd or in /etc/aliases.
Ok, I authenticate with full email addresses and there's not user1 on /etc/aliases... I've tried with another user and with non-encrypted passwords but still doesn't work. Do I need to configure DNS server or something that is not mentioned in the howto? Edit: I don't know if this is important but every time I restart courier-authlib I see this on /var/log/maillog: Feb 4 17:42:05 server authdaemond: stopping authdaemond children Feb 4 17:42:05 server authdaemond: modules="authmysql", daemons=5 Feb 4 17:42:05 server authdaemond: Installing libauthmysql Feb 4 17:42:05 server authdaemond: Installation complete: authmysql
