I’ve not yet tracked down exactly when and where this crept in, but recently when logging in to my web mail, I’ve been seeing an error message like this:
Could not log on to timsieved daemon on your IMAP server localhost:4190.
I was puzzled because I’d not knowingly changed any configuration for either Dovecot or Squirrelmail and Dovecot’s sieved was still listening right where I expected it to be on port 2000. After a little digging I found in /usr/share/squirrelmail/plugins/avelsieve/config/config.php this section:
/* ======================================================================== */ /* =================== ManageSieve Backend Options ======================== */ /* ======================================================================== */ /* Port where timsieved listens on the Cyrus IMAP server. Default is 2000. */ /** DEBIAN CHANGE: Despite upstream's intention Debian changed this default * distribution wide to 4190 which is thus default here. */
global $sieveport; $sieveport = 4190;
Well duh, thanks. Setting this value back to 2000 fixes the problem. Though perhaps, at some point, Debian will ship a default Dovecot configuration with the sieved on port 4190.
