Are ECC TLS certificates "production ready" or should I stick to RSA based certificates for mailservers?

Using email on the same domain on a Ghost installation on YunoHost

https://postcrescita.it is a wonderful #Ghost website curated by @ceci+comrades. It’s hosted on my community #server, powered by @yunohost.

How can I provide them one or more #email addresses using @postcrescita.it, that they can regularly use through a mail client, without compromising Ghost’s (required) email functionality?

Here is the related thread on the YunoHost forum.

If you are creating a new #mailserver and you need to migrate mailbox files to mail directories. How would you do it?

We are using #dovecot on both machines and want to try to migrate to #mailcow.

Erm, fellow mailserver hackers: did I miss something?

I was just told that I should use SHA256 hashes, rather than SHA512 for MTA DANE (meaning: eg 3 1 1 rather than 3 1 2).

Is this correct? I fail miserably at finding the corresponding RFCs.

The alternatives courier and cyrus both require me to start from scratch - with no guarantee that this might not happen again - quiet a bad feeling there…

That whole #dovecot breaking update (and from what I've seen the unreasonable pro version, at least for small setups) makes me question self-hosting my mail server…
I'm fine with investing time to setup something the first time - but updates (especially not minor) should never be breaking… - neither should they require quiet some time investment imho…

Since Dovecot 2.4 is dropping replication, I'll definitely need to rework my mail servers and those for BSDMail. I think I'll be going back to Cyrus, which I last used over 20 years ago. The problem is my memories have long faded, so it'll be like studying it again from scratch. And that makes me happy, because it'll be like learning something totally new!

Special thanks to @h3artbl33d for the heads up!
