courier-authlib removal

[skoinga]

Hi,

often, during upgrade of some ports (like perl, for example), courier-authlib is removed and then reinstalled, and I need to restart courier-authdaemond in order to make imapd functional.
It's a normal behavior or some my mistake in some configuration?

------------------------------------------------------------------------
backing up installed courier-authlib-base-0.63.0_2 before removing it
MGPMrUpdate 0.4.1_9 command: #10 of 14 cd /tmp && pkg_create -b courier-authlib-base-0.63.0_2
------------------------------------------------------------------------
restoring databases localProperty.command:cp /tmp/*.db /usr/local/share/portmanager
------------------------------------------------------------------------
removing old courier-authlib-base-0.63.0_2
MGPMrUpdate 0.4.1_9 command: #11 of 14 pkg_delete -f courier-authlib-base-0.63.0_2
------------------------------------------------------------------------
pkg_delete: package 'courier-authlib-base-0.63.0_2' is required by these other packages
and may not be deinstalled (but I'll delete it anyway):
courier-imap-4.9.3,2

Warning: Removing user courier will also delete any
undelivered mail in the mail queue directories!!!
Do *not* do it if you're upgrading and would like
courier to continue trying to deliver this mail.
