Summary: imap daemon appears to leak memory on FETCH command
Description:
I delivered several thousand messages to an account on a test server, and
set up an IMAP account in Thunderbird to access it. Thunderbird ran its
junkmail controls on the folder, which issues a FETCH command for each
message. I noticed later that the dbmail-imapd child process handling my
connection had used almost all of the system's free memory and swap.
As best as I can tell, the process usually doesn't free memory used after
a message is fetched. I'm attaching a text file containing top's output of
the process at 3 second intervals. The memory usage does drop a bit in some
of the intervals, but overall it gets large fairly fast.
Killing, or having dbmail restart the child process after 1 connection
does successfully free the memory, though. The pop server does not show
the same behavior.

I should have added about the top output that it's just a small sample,
over the course of about a minute and a half of a new process as I fetch
all the messages. It's not meant to show a process using all system
memory.
