Hello,
we're using postfix and cyrus imap on the same machine for internal
mail. Mail delivered by smtp to the machine is locally forwarded to the
imap server.
Currently all mail is handled by a domain provider. We fetch our
(external) mails via POP3 from the provider's server.
We'd like to extend the usage of this mailsystem in a way, that it will
1.) send all external mail,
2.) receive all external mail
*and*
3.) do an online backup of all mails that have been transferred.
1.) is easy to solve.
2.) What's the best solution here?
- we could forward mails from our domain provider to our
postfix machine. What happens if that machine isn't online
for a few days? Is there a solution that the mail is
regularly being fetched (every 5 minutes) from the
provider's server?
- what else do you suggest?
3.) The backup can of course be done by syncing the imapd's directory
regularly to another machine. Problem is that the backuped data
structure is an cyrus specific data stucture that can hardly be used to
restore lost mails. We'd like to have a solution that makes it easy to
restore lost mails and - if possible - is an online backup solution.
That means each mail the is delivered or received will automatically be
backuped while it's being handled.
Thanks for any suggestions.
If you have suggestions to use a different software environment for mail
delivery, please tell me.
Thanks and greets
Boris
