I'm confused about some entries in our spool file. Periodically, I see something like this:
09:09 00:29 SMTPD(012B01E0) [213.59.53.67] HELO bestsites.ru 09:09 00:29 SMTPD(012B01E0) [213.59.53.67] MAIL FROM:<[EMAIL PROTECTED]> 09:09 00:29 SMTPD(012B01E0) [213.59.53.67] RCPT TO:<[EMAIL PROTECTED]> 09:09 00:29 SMTPD(012B01E0) [213.59.53.67] ERR bcw4.bcwebhost.net invalid user <[EMAIL PROTECTED] kazan.ws is not one of our domains, so I take this as someone trying to relay through our server and I interpret the error message to mean that the server refused to relay. I should mention that we require SMTP Auth for relay. Where things get funny is with this entry: 09:09 12:57 SMTPD(0022021E) [216.210.176.234] HELO JLSRF01 09:09 12:57 SMTPD(0022021E) [216.210.176.234] MAIL FROM: <[EMAIL PROTECTED]> 09:09 12:57 SMTPD(0022021E) [216.210.176.234] RCPT TO: <[EMAIL PROTECTED]> 09:09 12:57 SMTPD(0022021E) [216.210.176.234] ERR bcw4.bcwebhost.net invalid user <[EMAIL PROTECTED] This appears to be the same error message, but this is a legitimate client who is using SMTP Auth. So I don't understand why she is getting this error message. What's more, this particular (test) message was sent to her personal AOL account, and she received it. So, in spite of the error message in the log, it looks like it went through. My questions: 1. Does the error message really mean that a illegal relay attempt was foiled? 2. Then why did Stephanie's message go through to her AOL account? 3. And why does she get the error message anyway? By way of background, our SMTP security settings are: check value sender (checked) and relay for addresses (which lists a few addresses -- most of our clients have addresses outside of our control). That's supposed to be enough to block open relaying, but IMail security is something I find confusing.
