The mailing list for listmasters using Sympa

[Olivier Salaün <address@concealed>]

Hi David,

The first message has clearly been rejected because the From: address is 
forbidden by the default 'loop_prevention_regex' parameter, see 
http://www.sympa.org/manual/conf-parameters/conf-parameters?s[]=mailer&s[]=daemon#loop_prevention_regex

However you should have had a log of this kind :

   Ignoring message which would cause a loop, sent by
   address@concealed

If not, you either have a problem with your syslogd or you are filtering 
Sympa log messages (note that not all error messages use the 'err' log 
level).

I don't see any obvious reason why the second message has been rejected 
; I suggest you first solve your logging problem.
