Hi, I have done configuration dovecot/exim/samba4ad. I use dovecot-lda not exim to deliver mail. And dovecot to authentify users. I have users with mail address on AD. When i sent mail to user mail address, its working. I have distribution group or group with mail address on AD and users as member of this groups. But when i send mail to group mail address, its not working Dovecot-lda can do it ? Or i need do it with exim (or postfix) ? Thanks Beno?t -------------- next part -------------- A non-text attachment was scrubbed...
