The mailing list for listmasters using Sympa

[Olivier Salaün - CRU <address@concealed>]

Hi Richard,

You can configure Sympa to define the maximum number of recipients per 
MTA call ('nrcpt' variable). This parameter makes sense with sendmail 
but I think that the modular architecture of Postfix breaks this logic. 
You probably need to tune your postfix server.
