Do not send email via SMTP POSTFIX by php scripts.

[Рясный_Павел]

The problem is, can not send mail via SMTP using popular scripts Opencart, SMF, Osclass.
The problem was lapping Plesk 11.5 via 587 port.
That was timeout connection or authorization error with the correct settings.
Mail may be sent, sometimes not. No longer working than working.
At the same time when working with e-mail clients(example, The Bat) work fine.
In Plesk 12 same problem. Port 465 - e-mail clients(example, The Bat) work fine.
But can not send mail via SMTP using popular scripts Opencart, SMF, Osclass.
When using Cpanel with Exim - all work perfect.
But the Plesk e-mail with Postfix - constant problems.
What is the problem and what to do?

In /usr/local/psa/var/log/maillog
There is nothing that could help.

In opencart error.logs :
PHP Warning: fsockopen(): unable to connect to
PHP Notice: Error: Connection refused (111)

"Connection refused" may be caused by firewall. In other case it should be "Connection timeout" Check netstat -anp to find out which ports are open by which process.

Hope this also helps:
