Hi guys.
Recently, a customer emailed me and had an issue like below
I have added the domain to whitelist. but I don't understand how this error occurs
Some emails coming from the domain still pass.
Example: ThaiNX3@fpt.com.vn
Someone please help me
I'm using mdeamon. i turn off authentication SPF in Mdeamon.
Thanks All.

The error message is explaining it:
Rejected by SPF: 210.245.0.187 is not a designated mailserver for fti.idchn.ticket%40fpt.com.vn

fpt.com.vn has a problem with their SPF record (if they want to send from 210.245.0.187 they need to include it in the SPF record)
-> This is something the mailadmin of fpt.com.vn needs to fix

If you want to whitelist them for SPF checks - you need to add them to the mailproxy whitelist (GUI->Administration->Mail Proxy->Whitelist)

see also:
https://pmg.proxmox.com/pmg-docs/pmg-admin-guide.html#pmgconfig_whitelist_overview

(you could also disable the SPF checks on Mail Proxy level GUI->Administration->Mail Proxy->Options)

I hope this helps!
