Plesk 11.x / Linux :: Failed Mail Authentication

Aug 12, 2014

Lately I've been spending a lot of time grok'ing the Postfix logfile (i.e., /usr/local/psa/var/log/maillog) and I've been noticing a lot of authentication failures (and even one successful break-in).

Most entries are just a simple pair of log entries that includes the source IP address and then the details of the mailbox name, like this one:

Code:
Aug 12 08:08:18 www postfix/smtpd[4805]: warning: unknown[162.255.86.250]: SASL LOGIN authentication failed: authentication failure
Aug 12 08:08:20 www plesk_saslauthd[4434]: failed mail authenticatication attempt for user 'media@example.com' (password len=6)

[Code]....

How are these entries generated? i.e., Why mailbox name given right away some times (like the first example) while - other times - the account name isn't displayed for several seconds - almost ninety seconds in the second example?
