So I've changed the user_query to include alias and it's actually working fine on my test environnement.

I'm not completely sure about that. If you want to use Dovecot's quota-status to reject message during SMTP session, Postfix' smtpd process needs to do that and - to my knowledge - it's only able to pass recipient address, not the aliases involved. I was looking for a solution to this few months ago as well. In the end I created sort of policy service proxy between Postfix and Dovecot. The proxy looks up aliases in database, converts them into real users and asks Dovecot about those. Final result is then reported back to postfix/smtpd.
Re: postfix alias and dovecot quota
I've the same problem. Dovecot can reply REJECT when Postfix ask for know the quota of the real user. But if the email it's alias, Dovecot does not know the email and reply DUNNO, but when the mail must be delivred by the LDA, Dovecot reject because the user it's over quota. I search since several weeks how to fix that and for postfix ask the quota-service with the real user email and not the alias. Because Postfix know the real user email because it's search it on the first time before ask Dovecot... I don't understand that postfix can't have a feature for check the quota-service with the real user email and not the alias... It's possible that I was wrong and not really understand the Postfix doku (that's really possible). If anobody have one idea that would be great, because I'm really lost, and I think i'm not alone :) Bests Regards, Nathan - Mail original - De: Jiri Bourek bou...@thinline.cz À: dovecot@dovecot.org Envoyé: Lundi 30 Juin 2014 13:37:26 Objet: Re: postfix alias and dovecot quota On 30.6.2014 12:33, Nick Edwards wrote: On 6/29/14, Alexandre Ellert aell...@numeezy.com wrote: Le 29 juin 2014 à 06:24, Nick Edwards nick.z.edwa...@gmail.com a écrit : it is the job of postfix to do this, aliases are just that, aliases of the real mail account, they do not exist in real storage, else, they would not be alias.

You’re not: http://www.postfix.org/SMTPD_POLICY_README.html#protocol If anobody have one idea that would be great, because I'm really lost, and I think i'm not alone :) One idea is to use the same data source for the userdb of postfix and dovecot. Mail alias data that postfix uses would then also become available for dovecot. Dovecot would then be able to correctly resolve mail aliases to users and provide useful quota information about the mailbox.

postfix alias and dovecot quota
Hello, Can someone tell me if it’s possible to configure dovecot to answer quota information about real mailbox when I query a postfix alias mailbox (this information is actually in a mysql database) ? Example : doveadm quota get - u al...@domain.com doveadm(al...@domain.com): Fatal: User doesn't exist doveadm quota get - u realmail...@domain.com Quota name Type Value Limit % user STORAGE 2048853 2048000 100 user MESSAGE6783 - 0 I’d like to have this result : doveadm quota get - u al...@domain.com Quota name Type Value Limit % user STORAGE 2048853 2048000 100 user MESSAGE6783 - 0 doveadm quota get - u realmail...@domain.com Quota name Type Value Limit % user STORAGE 2048853 2048000 100 user MESSAGE6783 - 0 Thanks for your help. Alexandre.
