Ipurge deletes messages from the mailbox(es) specified by mailbox-
pattern that are older or larger than specified by the -d, -b, -k or -m
options. If no mailbox-pattern is given, ipurge works on all
mailboxes. If the -x option is given, the message age and size MUST
match exactly those specified by -d, -b, -k or -m. The are no default
values, and at least one of -d, -b, -k or -m MUST be specified.
Ipurge by default only deletes mail below shared folders, which means
that mails in mailbox(es) below INBOX.* and user.* stay untouched. Use
the option -f to also delete mail in mailbox(es) below these folders.
Ipurge reads its configuration options out of the imapd.conf(5) file
unless specified otherwise by -C.
-f Force deletion of mail in all mailboxes.
