letsencrypt

[David Mehler]

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.
