When sending to
[email protected] via PHP mail() function, I receive mails.
When sending emails from external machines, I receive the following (e.g., sending from
[email protected]. [mail.ru is Russian gmail]):
This is the
mail system at host fallback2.

Why emails from external server are not being delivered? Thank you!
Update
In a log, the following lines appear a lot of times
Oct 30 10:48:29 mydomain postfix/smtpd[16216]: connect from fallback5.
mail.ru[94.100.176.59]
Oct 30 10:48:29 mydomain postfix/smtpd[16216]: warning: SASL: Connect to private/auth failed: Connection refused
Oct 30 10:48:29 mydomain postfix/smtpd[16216]: fatal: no SASL authentication mechanisms
It appears I have to configure SASL? I would understand if I would like to send emails from postfix, but why do I need it to receive emails?
