Hello
I'm a subscriber to a few Yaho groups, and recently have been
unsubscribed by them, automatically. When I view my Yahoo bounce history
I can see: "Last Bounced Message: Remote host said: 511 sorry, no
mailbox here by that name (#5.1.1 - chkuser) [RCPT_TO]"
Now I know that the mailbox is there, as it is my main personal email
account that runs through our qmail/vpopmail/chkuser/simscan toaster and
so the mailserver returning this message is an obvious error. However,
when I search the logs, I do find several bounces for my valid email
address, see log below.
When I look at our server monitoring for these days, I can see that
these erroneous bounces occurred on 19th April when the server was under
a high load, due to a targeted spam attack.
My question is, has anyone else noticed this as a problem, and also am I
correct in the assumption that this is more likely to be a vpopmail
error, rather than a problem with simscan or chkuser?
