Error Proxmox Relay Server "552 Virus found inside of the email (in reply to end of DATA command))"

[sanojs]

Hi Team,

Our customers are continuously getting below error while sending emails with attachments to my mail server. We have scanned and confirmed that the attachments don't have any issues.

From proxmox relay, mails are continuously bounced with the below messages. Is it due to the problem with the proxmox relay server filter issue ? or firewall issue?

Can someone assist with this?

host x.x.x.x [*.*.*.*] said: 552 Virus found inside of the email (in reply to end of DATA command))

Thanks
