sender address / reply address is rewritten

[ebag]

Hi,

I'm having the following problem:
All my outbound mail (new messages and replies to messages) has their headers rewritten so that the domain part of the adress (after the @) is the FQDN hostname of my scalix server, as in firstame.lastname@server.domain.tld.
This does not happen to internal mail (between two scalix users on the same server)

it was a masquerading rule in my /etc/sendmail.cf file
i've changed it now and it seems okay
