sendmail

A few days ago my mail server (fedora 10, running sendmail 8.14.3) started getting "Transport endpoint is not connected" messages in the log.

It seems to be happening for bigger mail hosts (hotmail, gmail, aol, etc).

The errors started happening about the same time I upgraded clamav ... so I just tried downgrading clamav to the previous version, but the error keeps happening. I was dubious anyways ... why a milter would effect sendmail's ability to connect with a remote server was beyond me.

If I force the mail queue's to run, the messages are delivered normally.

I had this happen once before ... and I thought it was related to a milter I had configured but wasn't using ... but that milter is not in use at all now.

Any suggestions?
