FATTACH_MAX_SIZE and Max Attachment Size isn't working

Content

Hi,

The value we have for FATTACH_MAX_SIZE is 41943040. The value we have for Mailboxes > Max Attachment Size is 31457280

However even with this, when sending a file, we get the error:

This message wasn't delivered to anyone because it's too large. The limit is 25 MB. 

Any idea why our limits are not being enforced?

Thanks,

JJ
