Issues With IMAP

[Vectr0n]

Hello,

I recently moved my CPanel server and xfered the account, everything is going well at this point, execpt I have one customer that is unable to download email using outlook 2003. All his settings are correct, but nothing we do will download the email sitting in the inbox. I was taking a look over the log messages, and I have noticed that when this user attempts to download mail the rip=127.0.0.1 and the lip=127.0.0.1. I am not seeing this for anything of my other customers, the ip of the customer shows. Please help..

May  8 11:12:35 vectr0n4 dovecot: imap-login: Login: user=<[email protected]>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured
May  8 11:12:36 vectr0n4 dovecot: IMAP([email protected]): Disconnected: Logged out bytes=764/4213
May  8 11:12:37 vectr0n4 dovecot: imap-login: Login: user=<[email protected]>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured

Thanks!

What you posted appears to be a webmail login log.

1. Have your customer tell you what his IP address is

If he doesn't know how to find it, tell him to open a web browser, go to http://www.whatsmyip.org, and then tell you what his IP is

Then grep xxx.xxx.xx x.xxx /var/log/maillog
- where xxx.xxx.xxx.xxx is his IP address

See what the logs say then

Also, have him issue a telnet session to his mail server POP3 and then let you know what the banner states.

telnet mail.xxx.ca 110

He should then see a banner that advertises itself as your server. If he sees some other banner then he is likely caching old DNS information and his Outlook is trying to connect to the old IP address to obtain mail. If he doesn't see a banner at all, then a firewall somewhere is blocking his outbound access to TCP 110.

Thanks very much for your help! Turns out it was cached DNS records. As i had suspected.
