[pmg-devel] [PATCH pmg-api 2/2] ruledb: content-type: do not rely on PMX_header_ct

[Stoiko Ivanov]

as noted in the cover-letter for v3 of the series introducing this:
https://lore.proxmox.com/pmg-devel/74a089b6-d858-4525-9822-da58b9c8f4d7@proxmox.com/T/#t

the PMX_magic_ct, PMX_glob_ct and PMX_header_ct are only set if there
is a bodyhandle for a mime-part, which only exists if the part has no
sub-parts.

However we want to match on content-types even for mail-parts which
have no bodyhandle:
* our internal regression-test suite has a mail with `message/partial`
  set
* there are probably sensible uses for matching `multipart/related`
  parts (e.g. when trying to get a negated match.

Noticed during a check of our regression-tests.

Fixes:
c320d56 ("utils: content-type: don't fallback to header information for magic")
