|
I'm currently working on a project that requires me to continuously pull all the new mail that arrives on an old Exchange 5.5 server and forward it to a new mailserver. Since I couldn't get Exchange 5.5's built-in mail forwarding options to work well, I opted to put up a separate box that just runs fetchmail continuously, pulling mail off the old server and forwarding it to the new server. My .fetchmailrc looks like this:
| Code: | .fetchmailrc:
poll old.mail.server with proto IMAP user "user1" there with password "pass" is user1 here options warnings 3600
poll old.mail.server with proto IMAP user "user2" there with password "pass" is user2 here options warnings 3600
...etc... |
And then I'm running fetchmail like this:
| Code: | | fetchmail -a -S new.mail.server |
This works great, but the problem is that it is only pulling mail from each user's Inbox, and many users have other custom folders with custom filtering rules set up in Exchange. I know that I could add a folder "Folder Name" parameter to my .fetchmailrc to have it target a specific folder in a specific user's account, but I need to do this for around 100 accounts, and I do not know who has custom folders and who doesn't, much less what they are all named.
So, my question is: is there a way to (1) tell fetchmail to download all mails from all folders in the account, or if not, then (2) do some sort of "IMAP query" on an account to generate a list of all of its folder names, and use that list to populate the .fetchmailrc file?
Thanks for any advice.
By the way, I don't care if mail downloaded from a custom folder would be deposited in "Inbox" on the new mail server after it is forwarded, so I don't need to worry about transferring the mail from custom folder to custom folder. |
