Re: Max RCPT TO: - option to negotiate?

1998-03-23 07:04:05
Does anybody see a need/desire/etc for an ESMTP option to advertise
this limit, so the upstream end can avoid sending a RCPT TO: that
will just get 452'd anyhow?

Straw man proposal:

250-MAXRECIP nnn    to state that more than nnn receipts will not be accepted.

FWIW, Zmailer says X-RCPTLIMIT n for some n, but I don't know what its
SMTP response is after n RCPT TO commands.

It -is- protocol bloat, and with ESMTP pipelining the extra commands
aren't terribly expensive, so it sounds marginal.
