Sophos XG Bug: Cannot send Backups using Amazon SES

Hello Rhys Goodwin ,

Thank you for reaching out to the community, SMTP error 554 indicates that the mail server did not accept the email. Several reasons typically cause this error: Invalid Recipient Address - There are invalid recipient email addresses; in rare cases, the recipient email address may have been suspended or disabled. It could also be BAD DNS record, blocklist, policy violation..etc. So verify the email address, SPF, DKIM or DMARC records, blacklist, syntax...

Please double check with the syntax, for further troubleshooting you can also a log a service request.

We have locked an investigation at: NC-133157.

I will watch this one with interest; one of our techs runs SFOS at home and found the same issue, and it really looked to him as some sort of issue with SES just flat out not liking these emails.  Other SMTP relay services worked fine.

Hi Vivek, thanks very much for your response.

In this case it appears that the message for backups being created by Sophos XG is not confirming to an acceptable level. The problem only occurs when sending backup files. Using the same SMTP server configuration and the same target email address, notifications and the test notification email is working correctly, so this is specific to backups.

I'm not allowed to log a support request as I'm a home user. However, as more people deploy Sophos XG to the AWS cloud, it will be important to solve this issue because people will want to use the AWS SES service for email.

Is there any way you could log a support case on behalf of this thread?

Kind regards,

Rhys

here the syntax is "0x000d0x000a name="Backup_[Serial]_SO01_SFOS-20.0.0-GA-Build222_31Mar2024_11.57.24" where semicolon is missing in the syntax, correct would be: "0x000d0x000a; name="Backup_[Serial]_SO01_SFOS-20.0.0-GA-Build222_31Mar2024_11.57.24"

Hi Rhys Goodwin  BrucekConvergent A similar investigation has been raised with the Development team and below is the ID details for the same.

NC-133157 - Cannot send Backups using Amazon SES, error: Expected ';', got "name"

I will keep this thread updated once I will have the next update ..!

Thanks team!

Hi Rhys Goodwin  BrucekConvergent  In the investigation this has been confirmed the Bug and fix targeted to Version 20.0 MR2 and 21.0. As of now, you may configure another email provider under notification settings like Gmail for a workaround in place of using Amazon SES until the issue is fixed.

Thanks very much Vishal.
