Yes, it resulted in 1500 files and further decoding was stopped.
Besides a mail bomb, it could just be a broken MIME mail
with lots (e.g. nested) boundary lines, which sometimes occur
when a mail loop is broken.

There was a problem with enforcing file limit during initial
MIME decoding, which resulted in deferring a mail, instead of
labeling it as a potential mail bomb and (by default) delivering
it, but wrapped in a message/rfc822 wrapper (defanged)
and a warning placed in the Subject and the first MIME part.
This behaviour was fixed in 2.3.2. From release notes:
BUG FIXES since 2.3.1:
- do not enforce $MAXFILES limit during MIME decoding to avoid tempfailing
mail; MIME parts are still counted, so an exceeded limit may still be
reported during subsequent decoding, but this is handled more gracefully
and does not cause preserved temporary directories to be left behind;
