After the last worm incident we got many complaints that mail is not
going through to us.
A quick log check showed that many messages from affiliate companies
are rejected because of bare linefeeds (we have a smtpd patch that
logs this).
Because the same companies were able to send mail to us before the
worm attack (and also after that) I doubt they changed anything in
their setup. Secondaries at our site are not involved (we have none).
The sending systems are Microsoft Exchange 5.5 and Sendmail 8.11. It
seems that they switch to bare linefeeds under load. Very mysterious.
Did anyone see this affect too?
