[SOLVED] Fetchmail from other servers (aka account aggregation)
NOTE: this should all happen on an MTA server, or the deliveries will fail (eg, server should be running the mta service)
I've attached a fetchmail config creation script to this post - remove the .txt extension, make it executable, and you can use this for account aggregation.
(All of this can be done as the zimbra user)
Here how it works - you use it to configure fetchmail to grab a number of external accounts, and deliver them to a local account:
This sets up 3 accounts - 2 IMAP from the same server (different folders) and a pop account from gmail (delivered to a different local user). The -k tells it to leave the mail on the server. Also, all of my accounts use SSL to connect - the '-s' flag. If you don't need that, you can omit it (but you'll probably have to change the ports, too).
zmfetchercfg -a -u firstname.lastname@example.org -H remote.server.com:993 -l email@example.com -p 'remote_pass' -s -P IMAP -f "Inbox" -k -c /opt/zimbra/conf/my_fetchrc
zmfetchercfg -a -u firstname.lastname@example.org -H remote.server.com:993 -l email@example.com -p 'remote_pass' -s -P IMAP -f "Work/Other folder" -k -c /opt/zimbra/conf/my_fetchrc
zmfetchercfg -a -u firstname.lastname@example.org -H pop.gmail.com:995 -l email@example.com -p 'remote_gmail_pass' -s -P POP3 -k -c /opt/zimbra/conf/my_fetchrc
chmod 710 /opt/zimbra/conf/my_fetchrc
To test it out
If everything looks good, remove the '-c' and it will really grab the mail.
HOME=/some/dir/I/can/write/to fetchmail -v -c -f /opt/zimbra/conf/my_fetchrc
Things to be careful about: the local account (-l option) needs to exist, or you'll bounce all your mail, which is bad.
Adding the -d option to the fetchmail call will cause this to run as a daemon, and periodically check your mail.
The folder options apply to the remote account, NOT the local account - if you want to control where it gets delivered, set up a filter.
Yes, this is horribly insecure. Yes, you're going to be storing your email passwords on disk in an easily readable format. This is more intended for the home/hobby user, not for any serious enterprise deployment.
Why can't we just use fetchmail?
I'm not sure yet how zimbra stores its mails,
but can't we just use the normal fetchmail tool
and make procmail drop the mail somewhere.
Because, currently, a lot of filtering is done with procmail on our systems
for mail fetched from other servers.
