I redirect an copy of my mails to my Gmail account. But the original message always remains in my provider's IMAP mailbox. To save disk space this script helps me to delete old emails automatically. This script was inspired by https://gist.github.com/Rathgore/2597705
from imapclient import IMAPClient, DELETED
import datetime
SERVER = 'imap.yourdomain.com'
USERNAME = 'mail'
PASSWORD = '1234567890'
FOLDER = 'INBOX'
MAX_DAYS = 90 # emails older than was deleted
