We run a small corporate mail server. Recently, we have been sending mail to a server, and the server always defers the mail with a 4xx code. This has been going on for several days. So, should we continue to send it? Why doesn't the server just reject it (5xx code)? This deferral is very confusing to our administrators.
Common reasons for deferrals - mailbox quota full - you are blocklisted - your (or their) DNS produces temporary errors - others does the deferral message explain why the deferral happens? -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
