After having used Pegasus 4.21 (I think it was) for a long time with no problem, suddenly a few days ago I started getting the error message "15: Peer connect failure (the host has refused the connection) when attempting to send email messages. One instant it worked. The next instant it started getting this message and I cannot send outbound messages via Pegasus. Incoming email works just fine.
My ISP had me run a check by testing webmail, and upon learning mail can be sent just fine, concluded it was not a problem with the ISP, leaving me to wrestle with what and how to troubleshoot Pegasus.
I just updated to the new version of Pegasus this morning. Again, incoming email works just fine. Outbound continues to get the error message.
I would appreciate guidance as to troubleshooting, references to any websites or other material that may help, or anything. I like and want to use Pegasus but I need to be able to send outgoing mail.
Thanks.
John
