Dovecot LDAP/AD with exim as mta

[Benoît PELISSIER]

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

Benoît
