imapfwd: forward mail to a main box
I have several email addresses but I want all messages to arrive in a single mailbox. imapfwd connects to an imap server and forward all unread mails to an other address through SMTP. Here are the recognized options:
$ ./imapfwd --help Usage: imapfwd [options] USERNAME IMAPHOST SMTPHOST DESTINATION Options: -h, --help show this help message and exit --pass=PASSWORD imap password -p PORT imap port --ssl use SSL for imap --prefix=PREFIX append a string to subject. ex: [box1]
I use the script in a cronjob. To set up the job, type crontab -e and add a line like this (I’ve saved the script in /home/pierre/bin/):
# m h dom mon dow command */10 * * * * /home/pierre/bin/imapfwd --pass or4nge mylogin imap.hmail.com smtp.isp.com mainbox@fmail.com
Here is the script:
