...>> a fully featured IMAP server. > Does the dumb server advertize pipelining? > Exactly how does an IMAP server advertise pipelining other than it says it's an IMAP server? :) There is no such capability, extension etc. It's in RFC3501, which defines IMAP v4r1. Dovecot has a proxy_nopipelining setting for its IMAP proxy, I just want to use that (ie: no pipelining) with imapc too. Whether it's dynamically configurable, even with the existing proxy_nopipelining, or with an imapc_features flag, it doesn't matter for me. Of course, setting this per user would be nicer.

Hi, I've a broken IMAP server, which doesn't support pipelining and fails on dovecot's attempt to do this ([C] is dovecot's imapc, [S] is the IMAP server): [C] 24 LOGIN "user" "pass" [S] 23 OK [C] 25 SELECT "INBOX" [C] 23 UID FETCH 2 (INTERNALDATE) [S] 25 OK [S] 23 BAD No mailbox selected Sadly, fixing the server would be a hard task, turning off

we have setup a two level proxy configuration for our zimbra server: [ dovecot 2.2.12 (imap proxy mode) ] V [ nginx (imap proxy mode) ] V [ zimbra imap server] and it does not work ... after tying a login, the connection just hangs and ends after 30 seconds with a timeout. - if I try again rightaway in the same dovecot connection, the login goes though without trouble.

Hi Philon, now, it's time for "Mahlzeit" ;-) Sorry, that I read the wiki1 instead of wiki2. I thought the 1 means that it is server one of ... my fault. Also not reading the first line above the menu. My focus was really on the content. ;-) Also my problem with the doc of Dovecot2 proxy is, that the document https://doc.dovecot.org/configuration_manual/authentication/proxies/
