This IS a forged Mozilla MUA header. The User-Agent field in your

it is from mozilla or compatible - apparently User-Agent: HTTP header sent
by browser ended up unmodified in mail.
If Horde wants to retain Web Browser headers, they can do so and wrap
them up in a References Email header.
apparently not References, that's supposed to contain referenced message-ids.
perhaps you meant other header?
X-Mailer?
Doesn't sound like Horde. Maybe more like a misconfiguration issue?
that's possible - I have filled up a ticket.
The only Mozilla MUA I know of is Thunderbird, and I regex on that
personally. The spin-off SeaMonkey doesn't set a User-Agent field.
I have just checked, both do:
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:60.0) Gecko/20100101
Firefox/60.0 SeaMonkey/2.53.8
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:78.0) Gecko/20100101
Thunderbird/78.11.0
(note that the one in OP is not from my client)
It's not a Mozilla MSGID.
Only question I'd have is on MSGID.
message-id was generated by horde, but horde didn't generate the User-Agent.
