David Harris has implemented ESMTP AUTH CRAM-MD5 for WinPMail, Mercury and Mercury/32.  They do a SMTP authentication in accordance with RFCs 2554 and 2195.  Mercury and Mercury/32 also do the LOGIN and the strange MS AUTH=LOGIN.

Go to File | Network configuration | (Sending) SMTP, edit the SMTP setup, select the "Security" tab and select one of the 3 options for doing SMTP Authorization.

This old guy finally got around to setting up a network connection at home betweeb the Pc and my laptop.

Everything seems to be workng okay except the mail. It seems I can receive but it won't send.I transferred

all settings exactly as they were on the PC to the laptop but still won't send I keep getting the same msg

Delivery has failed on the enclosed message for the following
reasons reported either by the mail delivery system on the mail
relay host or by the local TCP/IP transport module:

   550 5.7.1 Authentication Required

yet as I mentioned all settings were transferred exactly. I even tried using the wizard and entered network on one of the steps

Is there somethng speciaI have to do but overlooked? Any help would be appreciated.
