[Courier-imap] Error in IMAP command received by server

[Niklas Lampén]

Hello,

I'm getting errors like shown below. These errors shows to clients as
difficulties to connect to imap-server. Outlook "blings" (makes bling
sounds) and some times shows errors like "Can't open folder. Your root
folder is invalid" (something like that). This started to occur after
upgrading to more recent version and setting up postfix + courier-imap
to handle virtual domains with mysql. Funny thing is, that after a
couple of tries it allways works, so everyone is getting their mail.

If anyone knows what should I change (changing mail client is not an
option ;)) or fix, any help would be very valuable.

Replying to myself.

It seems that errors below are caused by incorrect imap handling by
Outlook. With Thunderbird everything works like a dream. Case closed.
Outlook closed.

Possibly you are exceeding the MAXPERIP limit (defaults to 4), if the client
decides to open multiple IMAP connections concurrently, as many bad ones do.

Errm, what version of courier-imap are you running? My guess is that it's a
prehistoric one. Try 3.0.4.
