Dear, I have Debian Squeeze + Postfix 2.7 as my mail server. Sometimes some users tell me they send a message and the recipient get 2 or 3 copies of the same message. At the moment they can't explain me what they have done in detail, so I need your opinion to have any idea of the cause of this behaviour.
The problem can be on Postfix or on the mail clientes (Thunderbird) ??? Thanks a lot
