Re: OT: need some advice as to distro

Always is the same: the best option is the best for you needs. So, the best could be any distro that you feel comfortable with. Obviously there're out there some distros which are server-oriented (CentOS, Debian) or desktop-oriented and so on, but really it doesn't matter. Choose your favorite

authdaemond / postfix issues after OS upgrade

I recently upgraded from FreeBSD 7.2 to 8.0. This resulted in a strange error with authdaemond (part of the Courier imap package, used to authenticate users) when used in conjunction with postfix; I've rebuilt all of the packages, but the config they're using has worked since the 6.0 days. I att

Force matching envelop MAIL FROM and "From" header

Hello is it possible to force a matching "From" header in the mail if reject_sender_login_mismatch is used so the "From" header is the same as the checked MAIL FROM address? The goal is to prevent spoofing of the "From" header for SASL authenticated clients. Many Thanks Andreas smime.p
