TMDA

   A question on TMDA.  I use the web-based email services of Burntmail.
   Burntmail supports POP, so I'm able to use the service through
   Outlook Express.  Burntmail supports TMDA and I like the service, it
   great!  I have all my contact email addresses in the White List so,
   that, only legimate mail comes through from those contacts.

   One thing that bothers me though.  And let me give you an example:  I
   send you an email with an attachment.  The email is sent back, either
   because your mail box has reached its quota or the attachment size is
   too large.  However, I will never know that the email is return to
   me, unless, I have the post-office's email address;
   i.e. [email protected] ; [email protected] in my White
   List.  How does anyone know what a post-office's email will be to put
   in the white list to have mail returned so that the sender's knows
   that the recepient did not receive the email and will be able to
   resend the email again?

Bounce messages are normally accepted.  This is what does it in my
~/.tmda/filters/incoming file:

	# Accept all bounces (messages with an empty envelope sender).
	from <> ok

You could see whether Burntmail enables this by sending email to (e.g.)
[email protected], which presumably doesn't exist, and see what happens.

   Note, however, that granting this exception for bounces does allow a
small amount of spam through.  Dealing with bounces will become a lot
more painful when the spammers discover this . . .
