Jim> Can anyone tell me what would cause the following error?

The Jim> error they receive on their end is.. Jim> No transport provider was available for delivery to this recipient. Jim> I've never seen either error before, and I'm totally stumped. I Jim> checked the sendmail FAQ, and there was nothing there about it either. Jim> Any ideas? The error on their end looks like it is coming from either Outlook or Eudora. Some poorly written MUAs have the habit of simply dropping the connect when the mail server returns an error. Since your syslog shows the problem is in collect, they must have gotten as far as the DATA phase. It could be an MTU problem as described in the FAQ: http://www.sendmail.org/faq/section3.html#3.10 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
