More or less (that option doesn't appear to be in the 2.4 branch....) There's also sieve_allowreferrals. > 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. The mupdate connection is routinely long lived. There is, however, no way to keep the connection to backends open beyond & between each user session. If you have a lot of short lived IMAP connections, you're probably interested in up-imapproxy. > Like a tcp keepalive. That's not what keepalive does... :wes ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
