I was given an opportunity to setup an email system for a friend that is similar to mine, so I figured I’d document this a bit better than what i’ve been documenting before.
As a primer, this is how we use sendmail, dovecot, and php to get email at a host and have it automatically move messages between email inboxes. Fairly easy 🙂
This should be a bit better than my previous partial writeups, specifically email.heick.email, sendmail & dovecot, how do you work…, and Dovecot IMAP (part 1).

With malice toward none, with charity for all, with firmness in the right as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation’s wounds, to care for him who shall have borne the battle and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves and with all nations.
– Abraham Lincoln, Second Inaugural Address, March 4, 1865
Continuation from Home Linux File Server
Challenges 9: Reinstall Core Operating system, configure it up, and mount and use /md.
The scenario is simple: We didn’t mirror our boot partition, so now we have to reinstall the operating system and make sure we can preserve everything we need to keep business consistency.

Challenges 6, 7, and 8: Break the RAID, again, Verify that we can still create/make files, and Rebuild the RAID with the Spare.
This is the crux of all of this. We need to be able to know that when a physical drive/volume fails that iSCSI won’t drop anything, that the RAID5 will still operate seamlessly in degraded mode, and that we can have the spare from our “Previously RMA’d drive” scenario take the place of the dead drive.
