Thanks for your comments.
I didn't think I had anything else touching the mailbox files. I use Outlook Express
on a PC which uses pop3 and SquirrelMail which uses imap. Pine is installed on the
linux box, but I rarely use it (and I guess it's safe). I contempated installing
spamassassin a while back, but didn't think I actually did it. However, I do see a
process "spamd" running. Hmmm.
Further looking indicates that spamassassin has been installed and running for a long
time. I'll try killing it, deleting all messages in my inbox, and see what happens.
Do you know if spamassassin is based on the c-client library?
Funny thing is the first such message I see in the log was reported on Sept 26th at
1:30pm. I was gone for the week prior to that (got home the 27th). My point is that
I couldn't have altered the configuration - even unknowningly. Since that point, I
get the message in my log file everyday - sometimes multiples messages in a day.
I did see the following message in the same log report, which I don't recognize...
Did not issue MAIL/EXPN/VRFY/ETRN during connection to MTA:
80.143.199.79 : 1 Time(s)
Could that be related?
