Re: Get username of local user from recipient address
Dne 28.12.2009 v 17:49 Wietse Venema napsal(a): Michal Kurka: Because I have not got any answer, I tried trace an internal communication between postfix'es processes via UNIX-sockets. I discovered that trivial-rewrite only specifies transport or does a canonicalizing. Process verify right tell that recipient address is alias to a concrete username. If recipient is aliased to more users, all usernames is announced. Now I'm trying use verify for my business. If simply execute verify, it ends with error message in Log fatal: service verify requires a process limit of 1. Sorry, you are playing with Postfix-internal interfaces. Use of these by non-Postfix programs is UNSUPPORTED meaning that it can break even after minor Postfix release changes. I aware of this. But do I have any other option? Unfortunately I haven't got any suggestion from anybody :-( -- Michal Kurka - Mysak sluzby spojene s operacnim systemem Linux

Unfortunately I haven't got any suggestion from anybody :-( Can't you just use virtual alias maps based on an external service for this purpose? For example in case of mysql you can create a stored procedure that 'logs' when the resultset is empty HTH Regards, Serge Fonville -- http://www.sergefonville.nl Convince Google!!

But I need a solution independent on used address mapping system on specific server. I administrate many MTA-serveres and on some isn't posible use MySQL or other external service. -- Michal Kurka - Mysak sluzby spojene s operacnim systemem Linux

Get username of local user from recipient address
Hello. I need resolve whether incoming mail for the recipient accept or defer or reject according to some rule of local username(s) (of course, if the recipient corresponds to local username), before SMTP-command DATA. My idea is create own policy service. But I don't known how get username of local user (or list of users) for recipient address. For replies in advance thanks -- Michal Kurka - Mysak sluzby spojene s operacnim systemem Linux
