Hello, I've been running dovecot for over 3 years now and it works with no problems. I have it setup so that it authenticates users against Active Directory via LDAP and so far no problems. What I would like to know is if there is any way that I could deny access for users trying to access email via cellphones or email clients outside the company. I can close everything since there are a few users that need to get emails from outside the company via cell phone of email clients. I was thinking if there was a way to lets say create a group in AD named: "remote-email" that will allow connection and authentication from any network, any user not in that group will only be able to authenticate if the source is 192.168.xx.xx/24. Is this possible? Maybe not with Dovecot, but maybe someone else has any ideas..? Thanks -------- Romer Ventura

There are certain users that will need to access their email from outside our local networks. This would work for half of what I would like to accomplish, the other half: "allow authentication for remote users as long as they belong to certain LDAP group" or something similar is what I am more interested on. Any thoughts? Thanks
