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
