POP3 Access through Dovecot with Outlook 2007


I have recently set up a mail system using Postfix, Dovecot, Spamassasin, ClamAV and atMail - I'm new at this, so proud of myself to have gotten this far. I have required secure authetication for both sending through SMTP and access via POP3 and IMAP. All seems to work properly. I have tested POP3 with KMail and Evolution and everything works great. The only problem is I cannot get Outlook 2007 to authenticate for POP3. I can send through SMTP with secure authentication from Outlook, but no matter what I try I cannot get it to authenticate for POP3 access. Checking SPA in Outlook causes it to repeatedly ask for credentials which it does not accept, while un-checking it causes the client to be immediately rejected by the server.

I have turned on all the various relevant client work-around options in Dovecot and Postfix (that I am aware of) and I have hunted through the web to see what I can find, but no luck.

Besides using the listed client work-arounds in the Dovecot config file, can anyone shed light on what else I might need to do to get Outlook 07 working with POP3?

Can post my config files if anyone wants to see them.

Thanks in advance.
James.

I think your issue is with Outlook 07 not the server. Check to make sure you have the right server address, and make sure you have the right port, as well as the right authentication, and make sure that your username and password are correct. I had this issue when connecting with Outlook 07 to an exchange box via pop3 same exact behavior. I had to change the encryption and change the email address. try username@domain.tld instead of just the unsername.

Hi,

Ports are all correct (and of course they work fine using other email clients). Have tried using the full domain name for username and that does not work either. Can send using authenticated connection through SMTP, but not if SPA is turned on. Setting SSL etc under 'Advanced' for POP3 also does not make any difference.

The log on the server shows (depending on what settings I use) either:

Disconnected: rip=xxx.54.58.14, lip=192.168.1.245

or

lost connection after AUTH from unknown[xxx.54.58.14]

or

warning: unknown[xxx.54.58.14]: SASL LOGIN authentication failed:

Got me then did you try searching for those errors? I connect to dovecote on an Ubuntu server in my DMZ with Outlook from my PC in the LAN with no issues, except for asking if I trust the cert I never have any problems.

Have Googled lots, but not found anything that specifically helps. Interestingly, Outlook has never asked if I trust the certificate - might be a clue. Thanks.
