"Disable non webmail IMAP access" in vpopmail and Dovecot
Hello, i'm using in my installation qmail+vpopmail and now I have migrated from courier-imap to dovecot. Dovecot is very much faster with large mailbox than courier-imap.

Patch for dovecot 1.2.16 (and .17) for vpopmail module
Hi Timo, I love dovecot but I love also vpopmail and its functions for manage user limits (via vmoduser). Unfortunately in dovecot 1.2.x auth default set to use "vpopmail" is unable to apply this limits. Only if used with checkpassword limits works fine but in the dovecot.log only user (without @domain) is logged. So, based on the code of dovecot 2.0, I have created this very

"service_count = 0" for "service dict" (High-performance mode)

Shared Mailboxes in a multi domain environment
Hi, I would like to enable mailbox sharing for my users. I'm using dovecot 2.1.9 with vpopmail authentication. For security reason shared mailboxes should be available only for users of the same domain. Dovecot's wiki suggest to enable acl like this: plugin { # assumes mailboxes are in /var/mail/%d/%n: acl_shared_dict = file:/var/mail/%d/shared-mailboxes.db } but in vpopmail,

Config questionsabout various login parms
I'm currently runing UW-IMAP (compiled vanilla) with procmail and mbox and am making my usual careful crawl (at turtle speed) through figuring out DC config. Some questions: a) I have something like 3-4 root imapd sessions so I presume that the default *login_processes_count* = 3 will be OK. I'm less clear about login_max_processes_count and login_max_connections = 256. A common

Dict quota timeout error: Has anything changed in the latest versions?
Hi, I'm using dict quota with mysql for track them via SQL query instead of read maildirsize file. Primary quota and enforcing is provided via userdb and is "maildir" type.
