I doubt it is the IMAP server. Currently top reports:
PID USER PRI NI SIZE RSS SHARE STAT %CPU %MEM TIME COMMAND
22449 jaldhar 9 0 18700 18M 2820 T 0.0 15.7 1:18 pine
23218 jaldhar 9 0 1836 1836 1540 S 0.0 1.5 0:00 imapd
With my debian-user folder open.
$ ls -la ~/mail/debian-user

This is uw-imapd-ssl incidently. More likely it is your email client and
the specific types of email you're getting (i.e. with big attachments like
you said) which is causing the bloat.
Btw IMAP fans, there is a new contender on the horizon--dovecot
(http://dovecot.procontrol.fi) It looks quite promising and I'll be
making packages available shortly.
