Postfix/smtpd - SASL Auth Problem

[nubduck]

Hi,

In short, when I try to send mails from Microsoft Outlook 2007, I keep getting prompted to enter username and password, and even though I know its correct, it just keeps poping up. Suspecting its the server, I checked the logs and found the following:

From /var/log/mailog:

Code:

Jun  3 03:41:30 hostnowwithus postfix/smtpd[3420]: connect from cm121.sigma50.maxonline.com.sg[218.212.50.121]

Jun  3 03:41:30 hostnowwithus postfix/smtpd[3420]: disconnect from cm121.sigma50.maxonline.com.sg[218.212.50.121]

Anybody has any ideas where I should go around fixing it?

Just update to my problem as above:
Using IMAP from the webmail client works fine, send and receive. Its just the SMTP when using with POP3 via Outlook 2007 so far.

Downloading other mail clients to test it out as well.

Other error logs I found while scanning through the log was this:
From /var/log/maillog

Code:

Jun  3 04:08:10 hostnowwithus postfix/cleanup[25495]: warning: database /etc/postfix/ispcp/aliases.db is older than source file /etc/postfix/ispcp/aliases

But it seems unrelated to the problem in #1
