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

Hey folks. One feature I'd really like to see in dovecot is the ability to point it at a database (with a configurable query) and have it allow or deny a connection based on looking up the source IP address in that database. I run Postfix, and I've got it configured to use a database server for its smtpd_client_restrictions checks. Ideally I'd like to point dovecot at

Hello, I like to enable the allow_nets Feature (http://wiki2.dovecot.org/PasswordDatabase/ExtraFields/AllowNets) for my customers. To help them knowing there own IP I imagine a special mailbox/loginuser at the pop3 server. That user could give a valid pop3 answer from a dummy pop3 server or simply throw a login error with customised answer containing the IP information. Has anybody done

Is there a way to restrict my user logins from a set of IPs? For example, all my users are in the US so there shouldn't be any logins from other countries. Can I tell dovecot to restrict logins to a CIDR list of US IPs? Can someone point me to docs on how to set this up? I've searched but haven't found how to accomplish this. Thanks, -Terry Terry Barnum digital OutPost

Thanks Benny. I should've said I saw AllowNets but in researching it looked like it expected a smaller comma separated list, not hundreds of IP blocks. Is that what you are using to accomplish this?

I have written a script that connects (localhost) to the dovecot/imap server and performs various maintenance on my mail, by folder..... deleting old stuff, keeping the n most recent, that sort of crap, er good stuff. :-) My script is written in php (I use the various imap_* functions), and it connects to the imap server running on the same machine... is there a way to connect to the server

I use dovecot, vpopmail. I wish to restrict a mail user's login to its mailbox according to its ip address. I don't wish other users to be affected . Namely, for instance, abc at domain.com can login to its mailbox from a few specific ip addresses but the same user will not able to login from anywhere. Meanwhile normally other mail users can login to their mailboxes from all ip

Dear all, We use `allow_nets`[1] to restrict login clients, it works fine. Recently we need to allow some users to login from everywhere except some IP/networks, how can we accomplish this with "allow_nets"? Tried allow_nets="!a.b.c.d", but Dovecot reports error "allow_nets: Invalid network '!a.b.c.d'". Can we have this feature? i guess it should be done

This was brought up in 2014, and left without conclusion, so I thought it would be time to bump it :) I would love a way to do allow_nets based on an RBL check, could this be added to the feature-list? https://wiki2.dovecot.org/PasswordDatabase/ExtraFields/AllowNets Thanks -- Tom

Hi, I have been reading the acl documentation and it seems that a "connect acl" is not available. I need to limit the users that can login in an IP number, is that posible with dovecot 1.0? (i.e. only these users can login from the Internet) Or a new plugin should be written? It is complicated to do that? Thanks Oliver -- Oliver Schulze L. | http://tinymailto.com/oliver Asuncion

G'day All, I am new to dovecot. I've run across the "allow_net" to restrict access on what seems like a per user basis. Is the a way to global limit access to one or more networks? Marcus O.

Hi I'm using dovecot imap with ldap accounts. User management interface is phamm. Internal clients connect directly using imap client. External clients must use webmail (squirrelmail). But not everyone is supposed to use webmail. Is there any way to control who is allowed to log in from a specific IP (webmail ip)? Thanx for suggestions Jan
