Postfix, emails stopped being sent.
The recent changes in postfix settings were related to SPF.
A couple of days later, it was discovered that emails stopped going out. There are no errors. The only thing in the log is, when trying to send an email - conversation with mx01.emig.gmx.net[212.227.17.5] timed out while receiving the initial server greeting.
