letsencrypt

Hello,

I know some users here are using letsencrypt for their CA. If this is to off topic write me privately.

I'm wanting letsencrypt to take over as my CA, replacing existing self signed certificates. I've got web working, a certificate for https sites and one for webmail as they have different names. What I'm now wanting to do is get letsencrypt going for my email setup, the smtp handled by postfix, but mail, and imap I believe are handled by dovecot.

With the web it was easy just let apache serve the token that letsencrypt needed and I got certificates. How do I do this with regards email?

I hope that's clear.

Any help appreciated.

Thanks. Dave.
