Re: everyone@example.com virtual_alias_maps using ldap query

[Ronie Gilberto Henrich]

Hi Reinaldo, The problem about your solution below is that it will go into a loop. 1) Loop: every...@example.com forward to us...@example.com and every...@example.com, which forward again to us...@example.com and every...@example.com, and again, and again, and again... If you are a developer of the project Postfix, is it easy to add support for variables (%u) on the left side? Example: everyone_query_filter = (&(accountStatus=active)(%u=everyone)) Thanks, Ronie -------- Original Message  -------- Subject: Re: every...@example.com virtual_alias_maps using ldap query From: Reinaldo de Carvalho <reinal...@gmail.com> To: ro...@ronie.com.br Date: Wed Mar 17 2010 08:19:47 GMT-0300 On Tue, Mar 16, 2010 at 10:38 PM, Ronie Gilberto Henrich <ro...@ronie.com.br> wrote: Hi Reinaldo, Let me explain better how virtual_alias_maps works in this case: 1) Someone send an email to every...@example.com 2) Query ldap:everyone result has to be us...@example.com, us...@example.com, and so on (all mailboxes in domain example.com) So, the %u value in everyone_query_filter is "everyone" Considering your suggestion: (&(accountStatus=active)(uid=%u)) and dn: uid=user1...: ================= Is "user1"="everyone" ? FALSE So, it won't return any mailboxes. Sorry, I misunderstand your question. Is not possible create "everyone" as you request. You need a cron job. Maybe... (don't tested) everyone_query_filter = (&(accountStatus=active)(mail=%s)) everyone_result_attribute = uid everyone_result_format = %...@example.com This work if you add attribute mail=every...@example.com for each ldap entry. dn: uid=user1...: uid=user1 mail=us...@example.com mail=every...@example.com dn: uid=user2,...: uid=user2 mail=us...@example.com mail=every...@example.com - Show quoted text - Considering also the second part of your suggestion, about adding the attribute mail=every...@example.com, it has 2 cons: 1) Loop: every...@example.com forward to us...@example.com and every...@example.com, which forward again to us...@example.com and every...@example.com, and again, and again, and again... 2) Redundant data, may lead to inconsistencies: no sense in having all mailboxes with a mail=every...@example.com. If one does not have every...@example.com, the result list of recipients of an email sent to every...@example.com won't be all (everyone) mailboxes.

I tried the following: everyone_query_filter = (&(accountStatus=active)(%u=everyone)) everyone_query_filter = (&(accountStatus=active)(uid=%u)) everyone_result_attribute = mail This work if you add attribute mail=every...@example.com for each ldap entry. dn: uid=user1...: mail=us...@example.com mail=every...@example.com dn: uid=user2,...: mail=us...@example.com mail=every...@example.com But it does not work. Is there any way to add that %u=everyone filter in the ldap query above? Or any other way to get the same results and still being dynamic? I mean dynamic by anything but generating hash alias_maps thru cron scripts. Thanks and regards, Ronie
