Thanx to everybody's help , i have got a working combination of; - dovecot LDA - smtp auth thru dovecot sasl - postfix - virtual users in mysql - postfixadmin - thunderbird as the email client Just 2 additional questions - A. Sieve .............. With the imap filters in thunderbird, do i need to use sieve in dovecot? my initial observations/ findings say "no"? B. Quota ............. If i have not set quota in dovecot or postfix ( no quota related configuration ), may i then assume, the users have "unlimited storage" , limited only by the hardware/filesystem? I would like to have this feature ( just like unlimited storage in yahoo ) and just have a cron script running regularly to delete old emails ( for middle level, low level users ). Is such a strategy ok? regards, mgomez

If you want to filter before the client has seen or downloaded the message, you need Sieve.> B.

Is such a strategy ok?This is completely up to you :) It depends on you user base, how they react upon "delete old mails". I wouldn't do so.

Several of our users have slow connections, therefore they want to see only minimal stuff in the INBOX, definitely no message the relay tagged as SPAM. They check out the other folders from their offices only. Client-side filtering would require them to download all messages, even SPAM, just to move them into a "not-urgent" folder never looked at. This is one example of server-side filtering. Initially I deployed a fixed Sieve script for everybody, which moved tagged SPAM into a SPAM folder, but more and more users wanted to hack their own.> Additionally what can i use sieve on the server side for?Well, current implementation is cmusieve, see: http://hg.dovecot.org/dovecot-sieve-1.0/file/1ddefc5e4e33/src/libsieve/README Dovecot v1.2 will support/use: http://hg.rename-it.nl/dovecot-libsieve/file/ab9a06342d33/README The basic language is the same, but there are different extensions supported.
