I'm getting this error when I add in the ip address in main.cf Code: Jun 28 14:24:04 server1 postfix/master[8683]: warning: process /usr/lib/postfix/smtpd pid 8773 exit status 1 Jun 28 14:24:04 server1 postfix/master[8683]: warning: /usr/lib/postfix/smtpd: bad command startup -- throttling Jun 28 14:25:04 server1 postfix/smtpd[8805]: connect from unknown[10.1.10.140] Jun 28 14:25:04 server1 postfix/smtpd[8805]: fatal: non-null host address bits in "75.147.237.114/29", perhaps you should use "75.147.237.112/29" instead Jun 28 14:25:05 server1 postfix/master[8683]: warning: process /usr/lib/postfix/smtpd pid 8805 exit status 1 Jun 28 14:25:05 server1 postfix/master[8683]: warning: /usr/lib/postfix/smtpd: bad command startup -- throttling Jun 28 14:25:30 server1 pop3d: Connection, ip=[::ffff:10.1.10.140] Jun 28 14:25:30 server1 pop3d: LOGIN, user=paulvang, ip=[::ffff:10.1.10.140] Jun 28 14:25:30 server1 pop3d: LOGOUT, user=paulvang, ip=[::ffff:10.1.10.140], top=0, retr=0, rcvd=6, sent=30, time=0 Jun 28 14:26:03 server1 pop3d: Connection, ip=[::ffff:10.1.10.140] Jun 28 14:26:03 server1 pop3d: LOGIN, user=paulvang, ip=[::ffff:10.1.10.140] Jun 28 14:26:03 server1 pop3d: LOGOUT, user=paulvang, ip=[::ffff:10.1.10.140], top=0, retr=0, rcvd=6, sent=30, time=0 Jun 28 14:26:05 server1 postfix/smtpd[8823]: connect from unknown[10.1.10.140] Jun 28 14:26:05 server1 postfix/smtpd[8823]: fatal: non-null host address bits in "75.147.237.114/29", perhaps you should use "75.147.237.112/29" instead Jun 28 14:26:05 server1 postfix/smtpd[8825]: connect from unknown[10.1.10.140] Jun 28 14:26:05 server1 postfix/smtpd[8825]: fatal: non-null host address bits in "75.147.237.114/29", perhaps you should use "75.147.237.112/29" instead Jun 28 14:26:05 server1 postfix/smtpd[8826]: connect from unknown[10.1.10.140] Jun 28 14:26:05 server1 postfix/smtpd[8826]: fatal: non-null host address bits in "75.147.237.114/29", perhaps you should use "75.147.237.112/29" instead Jun 28 14:26:05 server1 postfix/smtpd[8827]: connect from unknown[10.1.10.140] Jun 28 14:26:05 server1 postfix/smtpd[8827]: fatal: non-null host address bits in "75.147.237.114/29", perhaps you should use "75.147.237.112/29" instead Jun 28 14:26:05 server1 postfix/smtpd[8828]: connect from unknown[10.1.10.140] Jun 28 14:26:05 server1 postfix/smtpd[8828]: fatal: non-null host address bits in "75.147.237.114/29", perhaps you should use "75.147.237.112/29" instead Jun 28 14:26:05 server1 postfix/smtpd[8829]: connect from unknown[10.1.10.140] Jun 28 14:26:05 server1 postfix/smtpd[8829]: fatal: non-null host address bits in "75.147.237.114/29", perhaps you should use "75.147.237.112/29" instead Jun 28 14:26:06 server1 postfix/smtpd[8830]: connect from unknown[10.1.10.140] Jun 28 14:26:06 server1 postfix/smtpd[8830]: fatal: non-null host address bits in "75.147.237.114/29", perhaps you should use "75.147.237.112/29" instead Jun 28 14:26:06 server1 postfix/smtpd[8831]: connect from unknown[10.1.10.140] Jun 28 14:26:06 server1 postfix/smtpd[8831]: fatal: non-null host address bits in "75.147.237.114/29", perhaps you should use "75.147.237.112/29" instead Jun 28 14:26:06 server1 postfix/master[8683]: warning: process /usr/lib/postfix/smtpd pid 8823 exit status 1 I've tried it with outlook using Server Authenticate and without.

Use mynetworks = 127.0.0.0/8, 75.147.237.112/29 This link might be helpful for calculating networks: http://www.subnetmask.info/
Very Helpfull site for calculating it. My only concern was that I didn't try putting 75.147.237.112/29 because that IP was not given my me. My set of static IPs start from .113-.117 I'll try it and see what happens.
