    Posted: 08 May 2003 at 12:00pm

Is there a way of blocking e-mails that have garbage like in the below example? It says first that it was returned, then the next line says it was fowarded. So why did it do that?

 

05/08/03 10:55:51:998 -- (1104) Sending email from 国际微笑组织 to info@comtrol.com
05/08/03 10:55:52:128 -- (1104) EMail from: 国际微笑组织 to: info@comtrol.com  was returned to sender - server error - Syntax error in parameters scanning "FROM"
05/08/03 10:55:52:258 -- (1104) Error-email from 国际微笑组织 to info@comtrol.com  was forwarded to localhost
05/08/03 10:55:52:368 -- (924) Disconnect

The garbage in the "from" address comes from the "from" header in the email. SpamFilter is not currently verifying that, it only verifies the one indicated in the "MAIL FROM" smtp commands. It may be a good idea to scan the one in the headrs though, to avoid a situation like yours. We'll add it to the "to do" list.

FYI - the delivery attempt was not to your  info@comtrol.com account, but rather to the (bogus) sender of the email. SpamFilter forwarded the message to your SMTP server. Your SMTP server did not like the format of the email, rejected the email from SpamFilter, returning the error <Syntax error in parameters scanning "FROM">. SpamFilter then tried to notify the sender that there was a problem delivering his email, which also failed since the from was bogus.
