sorry for the old request, I am not really great with gihub as of yet :), I have redone the changes with some new formatting, change as you see fit

the main issue while I was configuring a new relay (namecrane.com) it does not currently support TLS on either 465 or 587 so I was attempting to get it working as a relay using SSL and this change was required to get it working

Jan 14 21:41:58 mail postfix/smtp[932]: SMTPS wrappermode (TCP port 465) requires setting "smtp_tls_wrappermode = yes", and "smtp_tls_security_level = encrypt" (or stronger)

I have tested it with purelymail.com on port 465 also,

with the option POSTFIX_RELAYHOST_SSL_ENCRYPTION enabled TLS will not work
