duncanc, I see you reply to many forum members, and glad to have folks like you around.
My problem is that that is the only line in my PHPlist Event Log. Others in this forum (including some of your replies) allude to a much more verbose set of error messages to use for troubleshooting.
c.f. dariuso in this forum exchange… SMTP connect() failed - #6 by duncanc
Is there anywhere else I might look for clues to my problem?
