OK . "proxyd_disable_mailbox_referrals" will be replaced to other parameter in new branch ( 2.4 )? In my work ( for policy reasons ) servers with mailbox can not be directly exposed to the internet. A Cyrus frontend is the best option because mailbox can exist in any internal server. And "shared folder" is very common in my enviromment. ------------------------------------------------------------------------------------------------------------ >> Is possible to force the frontends to keep the connectiom with >> MUPDATE and Backends ? > > If your frontend is configured as "unified", only mupdate will communicate > with the mupdate master.

If you have a lot of short lived IMAP > connections, you're probably interested in up-imapproxy. I believe that most customers will use Thunderbird and Outlook with IDLE support. And i think that this clients will keep connection open. Someone with more experience know if the thunderbird really keeps the connection open? Other question: IDLE imap command is compatible in Cyrus Murder enviromment ??
