It looks decent. If it fits your needs it should work. Spam control is via Spamassassin which is decent.

I use mail.com for mail forwarding and that works fairly well. Mail.com spam control is excellent. It is their own, not Spamassassin

define safety / security is far more than just if someone can read mail through visiting a webpage.

Email in general has NO safety or security. Virtually All E-Mail is sent un-encrypted, is completely readable to mail servers, certificates for SSL are never verified even if SSL is used. (This is not exactly a requiement).
On many mail systems the SYSADMIN can browse through files etc.

For secure mail... protonmail  might be your best bet.

The best thing would be e-mail sent using S/MIME or PGP where NON HTML/XML mail is used. (Just plain old ASCII).

the SYSADMIN can browse through files   <-- They would die of old age trying to find something useful in most mail systems.

I have not had issues this way. I am much more interested in Spam Control and no Ransomware.

I see (frequently) spoofed emails in my spam quarantine sometimes from the same people who send me legitimate email.

As noci asked, "define safety/security" + likely someone can assist you.

Be crystal clear, as email includes...

1) Arriving email (maybe you mean opportunistic TLS for incoming MTA connections).

2) Sending email (opportunistic TLS again, which you might force in some cases to only allow sending mail securely/encrypted).

3) Storing email (you're require an encrypted file system for this).

4) Reading email (which will simply mean wrapping your IMAP/POP server with an SSL cert).

@john: most mail systems are perfectly ordered, the system can find data for your mailbox... often times the mailsystem also keeps keyword lists, first scanning through the keywords lists is not to hard, then finding all mails with it is trivial... (otherwise web based mailsystem would be crawling).

Google scans all mails for user preferences in advertising targeting.
Microsoft scan all data for compliance to their TOS (at least).
Manually reading Peta bytes of mail is a joke, and probably will not be done,

I use rspamd and hardly see any spam anyway.. (kind of amavisd on steroids, verify effective with multi layered checks from valid senders, spamassassin, clamav, grey listing, SPF, DKIM, DMARC, generic blacklist checking, local blacklist, the exim mail verifies senders IP and validty there of.  )

Then about hostupd.  The only difference between those accounts are services provide for hosting. (SSL certificate available, Backup service provided).
I doubt if there would be a difference between the actual software used between the plans.

I do not disagree with you but people or software crawling through email needs to have a target and I am not that target. So I have set up my mail service to keep me safe from ransomware. As you undoubtedly read here, that is not trivial
