Looks like that is not your real FQDN. Did you setup hostname and FQDN according to the Perfecte Server Guide? Do commands Code: hostname hostname -f work like the guide says? So mail system works since you can send and receive e-mails? Was this set up just hours ago, so maybe the clients who could not send to your e-mail server had not yet received DNS name service updates about MX record? You wrote mail.log is OK. What exactly is OK? Do the emails arrive at your server but then do not go into mailbox? The sender should get some error message if the sending e-mail server can not send to your e-mail server.
Sir, My hostname is very much correct; hostname : server hostname -f : server.mydomain.com Sir, it was done almost 48 hours prior to server set up Further, it's been over a week now Sender is my bank email notification alerts, so can not check what message are they getting Thanks
Sir, Most of the emails coming to server and getting delivered except one from the Bank mail log is Aug 5 13:23:19 server postfix/smtps/smtpd[21876]: lost connection after AUTH from unknown[111.76.137.213] Aug 5 13:23:19 server postfix/smtps/smtpd[21876]: disconnect from unknown[111.76.137.213] ehlo=1 auth=0/1 commands=1/2 Aug 5 13:23:19 server postfix/smtpd[22039]: disconnect from unknown[185.137.111.00] ehlo=1 auth=0/1 rset=1 quit=1 commands=3/4 Aug 5 13:23:19 server postfix/smtps/smtpd[21934]: connect from unknown[111.76.137.213] Aug 5 13:23:19 server dovecot: pop3([email protected]): Disconnected: Logged out top=0/0, retr=0/0, del=0/40, size=1426454 Aug 5 13:23:21 server dovecot: pop3-login: Login: user=<[email protected]>, method=PLAIN, rip=106.201.7.135, lip=xxx.xxx.xxx.xxx, mpid=24061, TLS, session=<H1l871yPY8dqyQeH> Aug 5 13:23:21 server dovecot: pop3([email protected]): Disconnected: Logged out top=0/0, retr=0/0, del=0/69, size=28013763 Aug 5 13:23:28 server dovecot: pop3-login: Login: user=<[email protected]>, method=PLAIN, rip=106.201.7.135, lip=xxx.xxx.xxx.xxx, mpid=24063, session=<ck7q71yPpMlqyQeH> Aug 5 13:23:29 server dovecot: pop3-login: Login: user=<[email protected]>, method=PLAIN, rip=106.201.7.135, lip=xxx.xxx.xxx.xxx, mpid=24065, TLS, session=<+6f571yPEspqyQeH> Aug 5 13:23:29 server dovecot: pop3([email protected]): Disconnected: Logged out top=0/0, retr=0/0, del=0/12, size=8086437 Aug 5 13:23:30 server dovecot: pop3([email protected]): Disconnected: Logged out top=0/0, retr=0/0, del=0/179, size=50885784 Aug 5 13:23:32 server postfix/smtps/smtpd[21934]: warning: unknown[111.76.137.213]: SASL LOGIN authentication failed: UGFzc3dvcmQ6 Aug 5 13:23:32 server postfix/smtps/smtpd[21934]: lost connection after AUTH from unknown[111.76.137.213] Aug 5 13:23:32 server postfix/smtps/smtpd[21934]: disconnect from unknown[111.76.137.213] ehlo=1 auth=0/1 commands=1/2 Aug 5 13:23:32 server dovecot: pop3-login: Login: user=<[email protected]>, method=PLAIN, rip=106.201.7.135, lip=xxx.xxx.xxx.xxx, mpid=24067, session=<WcYt8FyPAdJqyQeH> Aug 5 13:23:32 server postfix/smtps/smtpd[21876]: connect from unknown[111.76.137.213] Aug 5 13:23:33 server dovecot: pop3([email protected]): Disconnected: Logged out top=0/0, retr=0/0, del=0/7, size=510305 Aug 5 13:23:34 server postfix/smtpd[21127]: timeout after AUTH from unknown[58.209.92.169] Aug 5 13:23:34 server postfix/smtpd[21127]: disconnect from unknown[58.209.92.169] ehlo=1 auth=0/1 commands=1/2 Aug 5 13:23:44 server dovecot: pop3-login: Login: user=<[email protected]>, method=PLAIN, rip=106.201.7.135, lip=xxx.xxx.xxx.xxx, mpid=24069, session=<j0XZ8FyPSM1qyQeH> Aug 5 13:23:44 server postfix/smtps/smtpd[21876]: warning: unknown[111.76.137.213]: SASL LOGIN authentication failed: Connection lost to authentication server Aug 5 13:23:44 server postfix/smtps/smtpd[21876]: lost connection after AUTH from unknown[111.76.137.213] Aug 5 13:23:44 server postfix/smtps/smtpd[21876]: disconnect from unknown[111.76.137.213] ehlo=1 auth=0/1 commands=1/2 Aug 5 13:23:44 server dovecot: pop3([email protected]): Disconnected: Logged out top=0/0, retr=0/0, del=0/21, size=2932064 Aug 5 13:23:44 server postfix/smtps/smtpd[21934]: connect from unknown[111.76.137.213]
