[K12OSN] weird maillog

[Barry Cisna]

Peter,

I've never used Qmail, but if I seen this error in Dovecot IMAP/POP
server, Id say somehow,there is a "virtuser" setting in your qmail.config
that is pointing to the IP address that is listed in your maillog.
Open your Qmail.conf file in text editor and search for the IP address
listed in your maillog,for a starting point.
Let us know if you advance any further:),,
