High CPU load, RCPT TO:

[Dirk Enrique Seiffert]

Hello,

I can't tell if this is a sendmail or a MailScanner problem: Certain mails are
causing a loop, making sendmail consume 99% of the CPU load. I have to
manually restart MailScanner. What they have in common:
1) Recipients don't exist
2) RCPT TO:

root     25608 74.3  0.5  8572 2556 ?        R    09:55  29:11 sendmail:
j11EtSBe025608 218.45.73.183.eo.eaccess.ne.jp [218.45.73.183]: RCPT TO:
<cesamir at caribenet.com>

logs show soemthing like:

SuSE 9.2,
mailscanner-4.36.4-1,
perl-spamassassin-3.0.0-3
spamassassin-3.0.0-3
sendmail-8.13.1-5

Does anybody know this problem or a solution?

Thanks

Enrique
