 Hi,

 i wondered why i never got emails from wordpress about my slack account
 and notifications etc.

 So i checked my mail-server logs and found the problem, the {{{smtp-
 fwd.lax.wordpress.org}}} has no rDNS set, so my mail-server rejected those
 mails.

 everything from {{{slack / chat.wordpress.org}}} goes over {{{smtp-
 fwd.lax.wordpress.org}}}, don't know if there are more services.

 I had to reconfigure my postfix and remove the option
 "reject_unknown_reverse_client_hostname" from
 "smtpd_recipient_restrictions" to get all those mails.

 As far as i know, on many mail-servers these option is active, mailcow has
 it in default active.

 Greetings
 Marcel
