Until recently my server with Postfix has worked well. Then I enforced some restrictions to a) combat spam b) disable sending emails to me on behalf on my own name.

And now I can't send email via my own postfix server.

 Client host rejected: cannot find your reverse hostname, [<my ip here>]

Note that I carry my laptot to different places and countries, and connect to WiFi from those. And I want to be able to send email always.

Here's a part of my config of Postfix. For database of the accounts and domains I use Postgresql.

smtpd_helo_required = yes

smtpd_client_restrictions =
 permit_mynetworks,
 permit_sasl_authenticated,
 reject_unknown_reverse_client_hostname,

 reject_unknown_client_hostname,

smtpd_helo_restrictions =
 permit_mynetworks,
 permit_sasl_authenticated,
 reject_invalid_helo_hostname,

### reject_non_fqdn_helo_hostname,

smtpd_sender_restrictions =
 permit_mynetworks,
 reject_sender_login_mismatch,
 permit_sasl_authenticated,
