I generated a new certificate for dovecot, and ever since I have this weird problem that my iPhone can still receive mail but cannot send using that mailserver. Same for my iMac.

Mail is not sent through Dovecot, but through an MTA. Based on your earlier messages I assume that's Postfix, and you should ask on the Postfix mailing list. See http://www.postfix.org/DEBUG_README.html if you want to receive an answer, folks on that ML tend to reply RTFM otherwise.

I'm wondering if there is any cache for a certificate or something

Apple Mail uses certificates from the macOS keychain. If you accept a certificate, it will be stored there.
