Emails with attachments of around 25MB in size are not reaching the instance although the instance is configured for higher limits. The maximum size of an email is restricted to 25MB at the Servicenow mail server. For more information, see the product documentation topic Email configuration.
Steps to Reproduce
Send an email to your instance that has an attachment of 25MB or larger.
Ensure that email message attachments are no larger than 25MB. Alternatively, you can use your own email servers for which different restrictions apply.
