encryption: TLS
pass: xxxx
Port: 587

Re: Its Safe this convination on postfix?

I fix this  adding DKIM.
and send wwhit php mail.
whit this  

Email picked up by Postfix locally goes through transport "pickup" (defined in /etc/postfix/master.cf). If you want to sign it, modify /etc/postfix/master.cf like this:

*) Find the "pickup" transport, like below:

pickup    unix  n       -       y       60      1       pickup

*) Append one line RIGHT AFTER it:

pickup    unix  n       -       y       60      1       pickup
  -o content_filter=smtp-amavis:[127.0.0.1]:10026

Warning: there must be at least one whitespace before '-o'.
*) Restart Postfix service.

With this change, ALL emails sent with 'sendmail' or 'mail' programs (or PHP mail function, etc) will go through Amavisd (sign DKIM signature, and more).

Don't do this change. leave it to "encrypt" for secure connection.
