What is the error message ?
Also look in file C:\Program Files\ALWIL Software\Avast4\Data\log\aswMaiSv.log for possible errors.

hi,
This looks like the error message from the logfile;
SMTP Closing connection due to PassThrough

For me its not really a problem as I don’t need to protect my mail but I am interested as I may well be recommending this program to others.

regards,
David
