Description
8451
-
Operation aborted: Local error in processing, try again later.
8500 - Command syntax error: The cause may be that the email server does not sup-
port the LOGIN authentication process. Check the parameters of TM_MAIL. Try
to send an email without authentication. Try replacing the parameter
USERNAME with an empty string.
8501 - Syntax error: Incorrect parameter or argument; you may have typed an incorrect
address in the TO_S or CC parameters.
8502 - Command is unknown or not implemented: Check your entries, especially the
parameter FROM. Perhaps this is incomplete and you have omitted the "@" or
"." characters.
8535 - SMTP authentication is incomplete. You may have entered an incorrect
username or password.
8550 -
The mail server cannot be reached, or you have no access rights. You may have
entered an incorrect username or password or your mail server does not support
log in access. Another cause of this error could be an erroneous entry of the
domain name after the "@" character in the TO_S or CC parameters.

Possible unreported email transmission errors

this case, there is no guarantee that additional recipients (with correct email addresses),
will receive the email.
