Increase permitted size of *received* messages?

[akahan]

Mail Server appears to be enforcing a maximum size of messages I can receive. A sender sending me a large message (I can't determine how big it must be to cause a problem) gets " 552 5.3.4 Message size exceeds fixed limit " in their bounce message from Mail Server.

Is there a way to increase the size limit?

Synology Mail Server -> SMTP: Maximum size per email (MB)

I set mine to 15MB as that's the maximum of my email service provider.

But isn't that the maximum size you can SEND? I'm referring to the maximum size I can RECEIVE.

It applies to both.

Some mail servers are even more stricter on the maximum size of received messages.

SMTP is for both sending and receiving mail. IMAP and POP are the mailboxes on the receiving server.

On the SMTP page it says "Enable SMTP to deliver and receive mails." So I'm thinking the size is for both.

Good point, @fredbert. I've tried it; will let you know the results.

Confirmed: Works.
