tidy pop accounts with quota

gistfile1.txt

#!/usr/bin/env python
# A very simple housekeeping script for POP accounts. fetchmail and getmail unfortunately don't
# have the option to delete old mail. They either 'pop and keep' or 'pop and delete'. If you have a mail
# account with quota this might be annoying. You'd like to keep as many mails on your server as possible
# just in case, but would like to avoid running out of quota.

# Edit this tiny script, save it in ~/bin with restrictive file permissions, since it contains your
# mail account credentials, and put it in your personal crontab.
# It is not very smart and makes no guarantees about that reserved space of your quota. If you
# receive a mail with a large attachment it might have to run a couple of times, deleting one old mail
# at a time, to free up some space.

import poplib

QUOTA = 15 * 1024 * 1024   # 15Mb Quota
RESERVED = 2 * 1024 * 1024 # 2Mb to keep free

# POP Server
server = poplib.POP3_SSL('pop.yourmailserver.com')
server.user('user@yourdomain.com')
server.pass_('secret_password')

mailboxsize = server.stat()[1]
print("Mailboxsize: %s kB" % (mailboxsize / 1024,))

if mailboxsize > (QUOTA - RESERVED):
    server.dele(1) # message number 1 is always the oldest mail
    print("deleting a mail to free up quota")
server.quit()
