Hello, I have encountered a delivery error with an MX that does not seem to be properly configured, and at the same time I noticed that exim *seems* to disregard lower numbered MXes.
These are the log lines: 2006-10-11 12:12:33 1GXazW-000KlD-1o => xxxxxx @repubblica.it R=dnslookup T=remote_smtp H=relay1.inet.it [213.92.5.56] 2006-10-11 12:32:07 1GXbNF-000KrE-So ** yyyyyyy @repubblica.it R=dnslookup T=remote_smtp: SMTP error from remote mail server after RCPT TO:<yyyyyyy @repubblica.it>: host relay1.inet.it [213.92.5.56]: 550 Unable to relay for yyyyyyy @repubblica.it. 2006-10-11 12:32:07 1GXbNF-000KrE-So ** zzzzzz @repubblica.it R=dnslookup T=remote_smtp: SMTP error from remote mail server after RCPT TO:< zzzzzz @repubblica.it>: host relay1.inet.it [213.92.5.56]: 503 need MAIL From: first. well, for one this inet.it server seems not to be able to relay for a domain for which it normally relays, unless it just gives the wrong error message. Also, it appears not to accept a second RCPT TO once a previous one was rejected. But I am not here to point out inet.it inadequacies... the point is that a couple of hours after this a dns check shows: dig repubblica.it mx ;; ANSWER SECTION: repubblica.it. 7925 IN MX 60 mr_trend2.repubblica.it. repubblica.it. 7925 IN MX 70 mr_trend1.repubblica.it. repubblica.it. 7925 IN MX 250 imail.repubblica.it. repubblica.it. 7925 IN MX 275 hide2.repubblica.it. repubblica.it. 7925 IN MX 300 relay1.inet.it. repubblica.it. 7925 IN MX 350 relay2.inet.it. repubblica.it. 7925 IN MX 10 mr_trend6.repubblica.it. repubblica.it. 7925 IN MX 20 mr_trend7.repubblica.it. repubblica.it. 7925 IN MX 30 mr_trend5.repubblica.it. repubblica.it. 7925 IN MX 40 mr_trend4.repubblica.it. repubblica.it. 7925 IN MX 50 mr_trend3.repubblica.it. ;; ADDITIONAL SECTION: mr_trend6.repubblica.it. 7925 IN A 213.92.86.56 mr_trend7.repubblica.it. 7925 IN A 213.92.86.57 mr_trend5.repubblica.it. 7925 IN A 213.92.86.55 mr_trend4.repubblica.it. 7925 IN A 213.92.86.54 mr_trend3.repubblica.it. 7925 IN A 213.92.86.53 mr_trend2.repubblica.it. 7925 IN A 213.92.86.52 mr_trend1.repubblica.it. 7925 IN A 213.92.86.51 imail.repubblica.it. 7925 IN A 213.92.86.95 hide2.repubblica.it. 7925 IN A 213.156.52.245 relay1.inet.it. 77637 IN A 213.92.5.56 and a look at both the SOA for that domain or a dig from another server shows that these records should have not changed: the SOA points to a serial from september and the dig point to a TTL of 86400 seconds, so the result of the dig above should be the same results that exim got when delivering. A look at the retry db shows: T:hide2.repubblica.it:213.156.52.245 60 333 Operation timed out T:imail.repubblica.it:213.92.86.95 60 333 Operation timed out so, again just attempts for the three lower priority MXes (as relay1.inet.it == relay2.inet.it). The logs show correct deliveries to the top MX on the 28th of September. Mmm, I am not at all convinced that this is an exim error, I am more inclined to believe that this is just the usual dns/smtp mess that some italian providers do so well..
