Splitting Exim mailboxes on two different disks

Question

I have inherited a rather small server and am forced to try splitting the e-mail accounts served by Exim on two (or more) disks (different mount points).

I was searching the internet for a solution but couldn't find one.

If at all possible, I want to be able to tell Exim on which mount point each e-mail address is and save accordingly.

Is this possible?

Thank you in advance!

Not enough disk space. The server is old, on FreeBSD. – Imuniser Jul 30 '23 at 12:58 — Imuniser, Jul 30 '23 at 12:58

I'm going to assume here that Exim is configured as a traditional internet MTA.

I don't think you can configure Exim to store mail in a separate mount point per user, but you can change where Exim stores the mail for all accounts.

Open the default config and change the file= (for mbox delivery) or directory= (for maildir delivery) directive in the local_delivery: section. The massively large default Exim config is typically /etc/mail/exim.conf.

Change the local_delivery transport to a mountpoint with sufficient disk space and copy/move the existing mbox files or maildir folders there.
