error

I am occasionally receiving error messages from mail servers with the above message. It seems that at least one line in the e-mail has more than 999 characters and therefore the e-mail is bounced.

Is this "by design"? in an RFC? Or some weird pseudo-spam-filter? Or just a bad mailserver?

I googled around a bit but did not find a competent answer. Hopefully one of you guys can enlighten me.
