5< 500 5.7.0 Unknown AUTH error -1 (Internal authentication error). As I can see, verison's SMTP server fails with a 500 "Internal authentication error". Can you deliberately feed it a wrong password and show us what the answer will be? Most probably, with DIGEST-MD5 a reply would be the same whatever the password is, so you would have to restrict AUTH to CRAM-MD5 in order to check for the wrong password reply. -- With best regards, xrgtn
