Hey everyone,

The following started showing up in my error logs:

Code: 
Jan 13 20:03:53 server postfix/smtpd[19081]: SSL_accept error from unknown[xxx.xx.xxx.xx]: -1
Jan 13 20:03:53 server postfix/smtpd[19081]: warning: TLS library problem: error:140760FC:SSL routines:SSL23_GET_CLIENT_HELLO:unknown protocol:s23_srvr.c:647:
Jan 13 20:03:53 server postfix/smtpd[19081]: lost connection after CONNECT from unknown[xxx.xx.xxx.xx]
Jan 13 20:03:55 server postfix/smtpd[19084]: warning: hostname server.eaglehomes.ca does not resolve to address 209.97.222.86
Jan 13 20:03:55 server postfix/smtpd[19084]: connect from unknown[209.97.222.86]

Where xxx.xx.xxx.xx is an IP address that is located on the server.

Any help diagnosing this issue would be amazing.

Luke
