Share Website certificate with SSL/STL Dovecot IMAP and Postifix SMTP
Hi guys,
I've bought a certificate from the authority for my website to use to access in https mode.
Is it possible to share the same pairs to authenticate the emails sent by postfix and Dovecot in order to avoid that client as Hotmail.it or Gmail intercept these as Spam?
Thank you

More about my SSL certificate problem

I think this was a special syntax-hack that Timo used to mean "read
into a buffer", or some different way to handle file data, probably
for security reasons.

regarding ssl certificates
With PKIX validation the certificate should match the hostname.
With SMTP, the hostname should match the reverse IP though often it does
not.
Using subdomains gives you flexibility.
with DANE validation, it is DNSSEC that validates the fingerprint to the
hostname so I do not believe there is a need for the hostname in the
cert to match anything, but DANE validation is currently not used by

Certificate cache on iOS with sending mail
I deleted the certificate already, but I think it only uses that for imap/dovecot. I don't think it actually stores one for smtps (or am I not talking sense here).

Dovecot IMAPS : Thunderbird SSL cert issue / Evolution OK
Evolution prompted to accept the cert; which I did.
Thunderbird used to prompt and allow acceptance; it no longer does...
well sorta does. See my other posting for a screenshot where it shows
"add server location https:// ...." HTTPS . no way to add from SMTP.
Have also tried typing smtp://host:25 and https://host:25

regarding ssl certificates
Is there some reason to use a mail.domain.com cert for mail rarher than just using domain.com for everything?
Historically the subdomain were used because they were on different hardware. That is www was on one machine and mail was on another.

I won't go over some of the excellent points in previous posts,
but I will mention SAN as a third type of certificate you can make.
LetsEncrypt supports this type of certificate.
This is halfway between single CN and wildcard certificate where you can
