Michal, Question,
I have been trying to send you email for a couple of weeks, have you gotten any of the messages?

If your AV filter knows to |simply discard infected messages from forging viruses, or all viruses, |most people ignore infection notifications, or have no clue what they |are being told (they already don't know how to install and maintain an |AV program, much less react to an infection). The problem is that I'm not writing antivirus, but content filter. Therefore, I'll reject all "*.exe" (etc.), withount even trying to = examine their content. Therefore, I can't simply blackhole the mail, withount = any notice. If the message is sent by virus, SMTP error is even better -- the virus = SMTP engine would not try to react to error, okay. When I'll send new error message, It will reach the forged sender of message. -- Altair - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED] - To unsubscribe from this list: send the line "unsubscribe xmail" in the body of a message to [EMAIL PROTECTED] For general help: send the line "help" in the body of a message to [EMAIL PROTECTED]
