3xx reply

["Donald E. Eastlake 3rd" <dee@xxxxxxxxxxxxx>]

This is really an RFC 821 question, but can anyone tell me what
typical SMTP clients do if they get a 3xx reply after a MAIL or RCPT
command?

RFC 821 says this is an "error" as opposed to a "failure" but do they
(1) abort the whole conversation, (2) give up on that piece of mail,
or (3) (for RCPT) just treat it like a failure and go on to the next
recipient, or (4) something else I haven't though of?

I'd appreaciate any info on this.

Donald

right now...)
