This my be entirely superstitious learning, but it seems like strange behavior.
I'm new to Mac OS X. Have used Mutt on Linux for quite a few years. I copied my .procmailrc, my .fetchmailrc, and my .muttrc pretty much intact from my old Linux box to my (leopard) mac. I set up postfix pretty much like on my old linux box (slackware). (By the way, mutt compiled out of the box on leopard -- no need for Fink or Macports.) I have a single machine, single user site connected by dhcp. Everything pretty much works. I finished setting things up on Dec. 28. Didn't turn on the machine again till sometime on the 31st. Strangely, I had no new messages since Dec 28. After checking that fetchmail was running, and looking at the /var/mail que with plain old mail, I sent a couple of test messages using plain old mail. voila! Suddenly mail appeard in the Mutt screen. Same kind of thing happened today. No new mail. After sending a test message from plain mail, the new mail showed up. I'd be happy if someone could point me where to look! Thanks! John Velman
