Thanks for your answer.
Don't know whether it is relevant to the particular issue, but i tried
both rulesets first with `scrub in all fragment reassemble` and
another one without it, but neither worked for me. I'm kinda upset by
the fact that pf can't handle large emails.

Any other ideas how to possibly fix it, please?
