[Mimedefang] long dns timeouts when first dns in /etc/resolv.conf is down

[Marcus Schopen]

Hi,

I had a strange behaviour this weekend: the first of two dns server of
my hoster in /etc/resolv.conf was down. The second dns server was
working. Mimedefang/Spamassassin didn't like that. I had very long dns
time outs for remote checks. It took over a minute for an email to run
through mimedefang. System wide dns worked fine, eg. like pinging
domains. After removing the "down" dns server from /etc/resolv.conf  and
restarting sendmail and mimedefang emails went through within a second
again. It shouldn't make a difference to mimedefang if one of the dns
server is down. Any ideas?

Ciao
