Hi Folks,
Sophos XG appears to have a bug where it doesn't interact with some SMTP servers properly.
In this case Amazon SES (Simple Email Services) cannot be used with Sophos XG for sending Backups. Other notifications work fine but backups generate the following SMTP error:
2024-03-30 22:57:43.705Z [1390] rTNXBs-m6OVmh-6I ** rhys@myemail.xyz F=<fwxg01@mydomain.com> P=<fwxg01@mydomain.com> R=router_for_notifications T=notification_smtp H=email-smtp.ap-southeast-2.amazonaws.com [3.24.9.22]:587 I=[123.124.125.126]:50972 X=TLS1.3:TLS_AES_256_GCM_SHA384:256 CV=yes DN="/CN=email-smtp.ap-southeast-2.amazonaws.com": SMTP error from remote mail server after end of data: 554 Transaction failed: In parameter list <0x000d0x000a name="Backup_[Serial]_SO01_SFOS-20.0.0-GA-Build222_31Mar2024_11.57.24">, expected ';', got "name" DT=1.168s
It appears that there is something malformed in the backup emails which is non-compliant with the SMTP protocol which AWS enforces rigorously.
I am running the free home license so cannot log a support call. This issue has been raised elsewhere in the forum, but we don't yet have a fix The value that the free license brings to the wider Sophos ecosystem is that tech enthusiasts like me, can spend our own time troubleshooting and diagnosing issues and then report them here in the forum. I know the Sophos team values the wider Sophos community so I do hope they will take the opportunity to improve the product for all and resolve this issue.
Kind Regards
Rhys
