[Dovecot] quota - implement via dovecot or postfix? which is easier ?
Guys,
i m new to dovecot. I m setting up a new mailserver and planning to run dovecot and postfix of a centos 5.2 box. I have been reading of quota management from various sources and understand that mail box quota can be implemented either thru postfix ( with vda patch ) or thru dovecot.
i rather not patch postfix and m therefore leaning towards quota via dovecot. But after reading some posts ,etc, it seems that the information on the dovecot wiki is inaccurate.
A.Any comments on this? B. Am i right in concluding that its easier and better in the long run to implement and enforce quotas thru dovecot instead of postfix? C. The right instructions for implementing quota thru dovecot?
Regards, marco.

Depends on your environment, requirements, and a number of other variables. I implement quotas through dovecot.
C. The right instructions for implementing quota thru dovecot?

If you enforce quota with postfix only, the quota effects mail deliveries via SMTP only, but not when IMAP users upload stuff.

Steffen, this i did not know. My understanding was that imap only reads what is stored, its is postfix and the LDA that actually writes to the mail box.

But with IMAP you can move messages in and out from other clients local stores, or from other servers entirely by drag and drop.

It also should be noted that many clients do this automatically with routine use, so users might not even understand that they are adding messages to their IMAP server, they might just know that they have Sent and Drafts folders.
