Subject:   sendmail pipe failing
Message-ID:  <v02120d42b1be5c639a73@[192.168.1.2]>

next in thread | raw e-mail | index | archive | help
I have a perl script which regularly sends mail out to dynamically
generated lists of up to several hundred people.  I've moved it over to a
freebsd machine and now have a problem.  Probably more to do with my not
having to deal with the details of sendmail in the past than it is to do
with freebsd.  My apologies if this puts it off topic.

basically I'm getting failures in a perl command which goes:


open (SENDMAIL, "|/usr/sbin/sendmail -t -oi") || die;


runs fine for smaller deliveries, but dies on deliveries af about 250
recipients, which I'm splitting into separate mail messages of 30
recipients each.

I suspect I'm running up against some limit that sendmail imposes to avoid
taking too much system resources.  There's plenty of cpu cycles to spare
though (Server load well under 1).  Is there a limit on the number of
sendmail processes which will run concurrently?  Any other ideas?
