I created an e-mail server, most emails to hotmail not arrive
Created 2 email servers configured with MX and PTR, SPF apparently correct. I can send emails to various servers including gmail, hotmail but users do not receive the email.
In my log shows that he was sent to the queue, but without error, and the recipient does not receive hotmail.
Follow the log:
Jan 27 23:19:46 mailm2m postfix / smtp : 951AE4176B: to = <email@example.com>, relay = mx4.hotmail.com [18.104.22.168]: 25, delay = 1.9, delays = 0.02 / 0.07 / 0.66 / 1.2, dsn = 2.0.0, status = sent (250 <firstname.lastname@example.org> Queued mail for delivery)
What can be?
