Hello, can courieresmtpd validate existence of mail addresses in the domains that are not local (listed in hosteddomains/locals)?
We want to split SMTP servers from MX servers, and I'm curious if it wouldn't result to accepting recipients that don't exist and are reject by "550 user <...> unknown" messages. We may distribute users' lists onto the SMTP servers of course, but we'd like to keep delivery on the MX servers. Another question is - can courieresmtpd validate existence of addresses provided in mail from: in the same way as it validated rcpt to: ? E.g. if rcpt to:<[email protected]> is rejected with 550, mail from:<[email protected]> could be rejected with the same error. Of course this can be only applicable to locally known domains. And btw: can courier reject non-existing domains in rcpt to: even for users with relaying privileges? mail from:<> nonexisting domains is rejected (if BOFHCHECKDNS is 1). However rcpt to: is not validated the same way, so it's quite often that users send mail to nonexisting domains. ... we are using a bit old courier, so it's possible that this is already implemented. However I haven't seen any mention of these... -- Matus UHLAR - fantomas, [email protected] ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
