It seems pointless - why accept a mail of size X only to reject/ignore it because it's greater than size Y.

Yep, you are right Tim. Chin put back up :)

I have two different scenarios:

1.  run /usr/bin/rspamc learn_spam, but have rspamd ignore large messages. Although I can use find /mailstore/path/ -type f -size -100M to get around this.

2. One of the rspamd processes crashes a while ago and I’ve not have time to replicate this. I wondered what if the MTA did not trigger values set by message_size_limit before the "Postfix Before-Queue Content Filter". Because I did not have time to investigate this and wanted a quick fix, I thought I would ask a Yes/No question: Can message size be limited in rspamd?  

Hope this all makes sense.
