With Mozilla recently dropping support for all Symantec certs, our security cert now throws errors on Thunderbird clients. We’d like to install certbot on Centos 6, but I’m not sure if it’s going to interfere with Postfix (2.11) or Dovecot (2.2.18). Does anybody have experience with
this?

I have no problem with Let's Encrypt certificates and postfix/whatever. I'm just not sure if iphones have the root CA (DST Root CA X3) installed -
just yesterday noticed a complaint.

But I prefer dehydrated over bloated certbot.

I also can confirmation that LE certs work just fine, and that acme.sh (https://github.com/Neilpang/acme.sh) is another working alternative to certbot. If you use DNS verification, you may prefer its bundled 'hook scripts' for various DNS APIs over the dehydrated model of listing the many scripts written by 3rd parties.
