I see you are running 6.03 - have you applied the smtp-auth patch? If not, get it here: http://www.ipswitch.com/Support/IMail/news.html You can also upgrade to 6.04 which should include the auth patch also. Both are free. Funny thing about the auth problem is that it will creep up for no reason one day, only effect a handful of users, then disappear. -- Scot ----- Original Message ----- From: "Matthew Goheen" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, October 03, 2000 5:23 PM Subject: [IMail Forum] SMTP-AUTH failing after firewall installation? > It may be coincidental, but suddenly my two co-workers can no longer send > mail using SMTP-AUTH.
