OK... had the user change to port 587. The problem still occurs. What is particularly confusing is that it is **ONLY** one or two users of several hundred on my server. In this particular case, I have 2 users on the same domain (husband & wife), traveling, using a Verizon mifi. SHE is getting these errors... HE is not. She is using either an iphone or her laptop with Outlook 2010. He is using his netbook with (as I recall) Outlook 2003. (or Outlook Express). I had her change her SMTP port to 587 and also turn on "my server requires authentication." But it still happens from her outlook account. _______________________________________________ Blueonyx mailing list Blueonyx@mail.blueonyx.it http://mail.blueonyx.it/mailman/listinfo/blueonyx
