Kick Back Email Issue

[Tanner2452]

Hi, so I should start this off by saying that our company does not use Proxmox. However, with a couple of our customers we cannot send emails back and forth. They are being kicked back with a spam filter message. Their IT persons say it's not on their end but the kickback is coming from a proxmox spam filter. I've done a bit of research on this product and have found that we may need to be added to a white list? Any help would be appreciated. Below is the text that gets sent back to us whenever we message them.

Your message could not be delivered for more than 4 hour(s).

It will be retried until it is 5 day(s) old.



For further assistance, please send mail to postmaster.



If you do so, please include this problem report. You can delete your own text from the attached returned message.

well, who is running the Proxmox Maligateway instance? The question is why the mail got SPAM filtered and that's something the people running the Proxmox Maligateway instance should be able to check in the logs.
