Protection by GeoIP was intsalled on smtp server smtp.forpsi.com to prevent abuse of email accounts for spamming.
Our experience shows that spammers mostly send spams from foreign IPs. Thanks to the GeoIP protection, we manage to filter a lot of connections which spammers try to establish.
Here is the list of allowed countries. All email accounts can login and send emails from these countries.
If you send from other country, you can get this error:
5.1.0 <firstname.lastname@example.org> sender rejected GeoIP mailtest.cz:22.214.171.124:CN
What to do if you get this error message:
Contact our customer support with chat or ticket on portal support.forpsi.com . We will allow requested country after your authorization.
Note: It can happen that if you travel abroad, you can't to send your emails, although sending from the country is enabled. The reason can be blocked communication on the port 25 from the Internet service provider. We recommend you to use the port 587, or the port 465 with an encrypted connection (SSL) for the SMTP server.
