Bug#894729: cyrus-common: cyrus-imapd fails with a syntax error if the squatter lines are uncommented in cyrus.conf

[Armando Vega]

Package: cyrus-common
Version: 2.5.10-3
Severity: normal

Dear Maintainer,

   We were provisioning a new mailstore using cyrus-imapd and decided to
   use the default squatter invocation lines provided in the cyrus.conf.

   We used the lines with the squatter invocation in the
   provided-by-default cyrus.conf file and restarted cyrus-imapd.

   The cyrus-imapd service failed to start complaining about a syntax
   error, explicitly mentioning problems with the '_' sign, which is
   used in the squatter name, e.g. 'squatter_a' and 'squatter_1'.

   We expected the cyrus-imapd service to start normally and do
   squatting as configured.

   As we have multiple mailstores with older versions of cyrus-imapd
   (2.4) we noticed that the syntax issue was only occuring on the newly
   deployed stretch-based ones with cyrus 2.5. It seems the syntax changed
   somewhere in between and the default provided cyrus.conf file didn't
   account for that. Simply changing the name not to include the '_' sign
   fixes it and the service runs as expected.
