Hi All Version: IMail 8.15
I have seen A LOT of emails being return due to fail connections. When we check on the MX records of the receipients the record IP is different to the MX. For example - the log shows the IP address for the site and not the MX record IP address resulting in failure - 03:10 10:42 SMTP-(0000000000000000) Info - Adding Queue file E:\IMail\spool\QHE48d4000005b8d7d5.VAC 03:10 10:42 SMTP-(48d4000005b8d7d5) processing E:\IMail\spool\QHE48d4000005b8d7d5.VAC 03:10 10:42 POP3D (00000df0) logoff for djohnson R:1, D:3, P:0, RS:4858 03:10 10:42 SMTP-(48d4000005b8d7d5) [x] Connecting socket to service <DNS> on host <63.175.158.253> using protocol <tcp> 03:10 10:42 SMTP-(48d4000005b8d7d5) [x] using source IP for mail.gemradio.com [192.168.1.5] 03:10 10:42 SMTP-(48d4000005b8d7d5) Connect 63.175.158.253 [63.175.158.253:53] (0) 03:10 10:42 SMTP-(48d4000005b8d7d5) [x] looking up AIG.com by stack 03:10 10:42 SMTP-(48d4000005b8d7d5) [x] looking up AIG.com by stack 03:10 10:42 SMTP-(48d4000005b8d7d5) closed E:\IMail\spool\_HE48d4000005b8d7d5.~AC - 1 03:10 10:42 POP3D (00000C8C) logon success for David.Johnson mail.gemradio.com from 10.110.15.8 03:10 10:42 POP3D (00000c8c) logoff for David.Johnson R:0, D:0, P:0, RS:0 03:10 10:42 SMTP-(48d4000005b8d7d5) R<[EMAIL PROTECTED]> - 1 03:10 10:42 SMTP-(48d4000005b8d7d5) R<[EMAIL PROTECTED]> - 1 03:10 10:42 SMTP-(48d4000005b8d7d5) [x] doing direct send AIG.com 03:10 10:42 SMTP-(48d4000005b8d7d5) Trying AIG.com (0) 03:10 10:42 SMTP-(48d4000005b8d7d5) [x] Connecting socket to service <SMTP> on host <AIG.com> using protocol <tcp> 03:10 10:42 SMTP-(48d4000005b8d7d5) [x] using source IP for mail.gemradio.com [192.168.1.5] 03:10 10:42 SMTP-(48d4000005b8d7d5) [x] Connecting socket to service <DNS> on host <63.175.158.253> using protocol <tcp> 03:10 10:42 SMTP-(48d4000005b8d7d5) [x] using source IP for mail.gemradio.com [192.168.1.5] 03:10 10:42 SMTP-(48d4000005b8d7d5) Connect 63.175.158.253 [63.175.158.253:53] (0) 03:10 10:42 SMTP-(48d4000005b8d7d5) Connect AIG.com [167.230.22.20:25] (2) 03:10 10:42 SMTP-(4807004d00d09d70) ldeliver mail.gemradio.com Ryan.wallace-main (1) [EMAIL PROTECTED] 1300431 03:10 10:42 SMTP-(4807004d00d09d70) finished E:\IMail\spool\Q4807004d00d09d70.SMD status=1 03:10 10:42 SMTPD(48d8004e00d09d7d) [192.168.1.5] connect 201.228.136.24 port 1689 03:10 10:42 SMTPD(48d8004e00d09d7d) [201.228.136.24] HELO servidor 03:10 10:42 SMTPD(48d8004e00d09d7d) [201.228.136.24] MAIL FROM:<[EMAIL PROTECTED]> 03:10 10:42 SMTPD(48d8004e00d09d7d) [201.228.136.24] RCPT TO:<[EMAIL PROTECTED]> 03:10 10:42 SMTPD(48d900a900d69d7e) [192.168.1.5] connect 88.84.200.97 port 1855 03:10 10:42 SMTPD(48d8004e00d09d7d) [201.228.136.24] E:\IMail\spool\D48d8004e00d09d7d.SMD 1270 03:10 10:42 SMTPD(48d8004e00d09d7d) performing antispam checks 03:10 10:42 SMTPD(48d900a900d69d7e) [88.84.200.97] EHLO [88.84.200.97] 03:10 10:42 SMTPD(48d900a900d69d7e) [88.84.200.97] MAIL FROM:<[EMAIL PROTECTED]> 03:10 10:42 SMTPD(48d900a900d69d7e) [88.84.200.97] RCPT TO: <[EMAIL PROTECTED]> 03:10 10:42 SMTP-(48d4000005b8d7d5) 421 SMTP service not available, closing transmission channel 03:10 10:42 SMTP-(48d4000005b8d7d5) SMTP_DELIV_FAILED 03:10 10:42 SMTP-(48d4000005b8d7d5) >QUIT 03:10 10:42 SMTP-(48d4000005b8d7d5) 03:10 10:42 SMTP-(48d4000005b8d7d5) [u] closing socket (u) 03:10 10:42 SMTP-(48d4000005b8d7d5) R<[EMAIL PROTECTED]> - 4 03:10 10:42 SMTP-(48d4000005b8d7d5) R<[EMAIL PROTECTED]> - 4 03:10 10:42 SMTP-(48d4000005b8d7d5) requeuing E:\IMail\spool\QHE48d4000005b8d7d5.VAC R0 T1 03:10 10:42 SMTP-(48d4000005b8d7d5) finished E:\IMail\spool\QHE48d4000005b8d7d5.VAC status=3 We receive mail ok - I guess. My question is how does the SMTP work what does it check for the MX or IP of the domain? I know it would use a DNS server to resolve addresses but what does it ask for? Are we missing something?
