The mailing list for listmasters using Sympa

[Dilyan Palauzov <address@concealed>]

  Hello,
  For the sake of completeness, it is worth to mention, that a reason  
for the blacklisting are the bounces sent by ML-software.

  I personally don't care how exactly the bounces are reduced, as far  
as this is done, preferably in a standard way.

  The idea of using sieve-filters is not universal, however it makes  
sympa compatible with any MTA that is sieve-compatible. Yes, usually  
sieve is applied during the LMTP dialogue, however this does not have  
to be the case -- putting Sieve (as smtp-milter) on the right place  
will produce smtp-rejects (cause the sendmail filter acts -before-  
closing the connection).

  With "not universal", I mean it cannot be checked, e.g. the validy  
of included certificate in a e-mail, but there are many cases, when it  
can be smtp-sieve-foreseen, that a mail will be definitely rejected by  
sympa. And this are the cases, leading to blacklisting )I guess, the  
real spam does not include [invalid] certificates).

  As I said, I don't care how will this idea come true, as far there  
is a way to smtp-reject undeliverable messages. Just to add, that  
'sympa.pl --test_authorization' shall return the same error message  
(to be added in the smtp-dialogue), that would be included in its  
bounce.

  Greetings,
