Re: Blacklisted by FortiGuard (Being looked as a spammer?)
My suggestion depends upon that you have an unused public IP address at your disposal. Probably, you will have to talk to your ISP first.
The mailserver's public IP address is published via an "MX record" which is part of the information distributed by DNS. Often, your ISP will provide DNS for you as well, but not necessarily.
If you've got an unused public IP address, you need to
- have the MX record changed to this new address
- update the FortiMails configuration to the new (WAN) address
- depending on your setup, change the destination NAT on your Fortigate if your FortiMail is behind the firewall. A DNAT object in FortiOS is a VIP; the 'external' address will be the new one, the 'mapped to' address will remain the same, internal address of your FortiMail.
Honestly: this is not something that you do light-heartedly, it's more of a desparate step. I hope your current mailserver address will be de-listed soon, that would be much less effort.
