Hi,

I have a littel Problem.

I?m running a Debian Lenny/Postfix/Dovecot Server. I hade immigrated from Courierer.

Now I have the problem, that I get mail under Mail.app double. (same header, Message-ID ,...)

When I use Thudnerbird under MacOS there is all OK.

Are there some Configs that I need to make for MacOS / Mail.app ?

I use IMAPS with all the clients (pop3 is only for 1 account - a Ticketsystem)

Thanks, Gerhard
