Dear diary,

Last night I migrated my mail server to a more current environment. That was so surprisingly painless, I’m now considering migrating my remaining CentOS 6 machines and become an official all CentOS 7 shop.

Most of the time was spent on migrating the mailboxes and generating new secure dhparams; fuck logjam, generating 4096 or 8192 bit dhparams is a PITA.

I’m sure you’re happy to know this.
