Sophos Email Security rejecting emails due to size limits

Ninjatech1969

Hello,

We have a client that sends large attachments, and Sophos is failing to send it. Is there a way to get around this? M365 allows you to be able to send 150 MB now.

I know I dont recommend this to clients . But that is what we have in this particular scenario.

relay-us-east-2.prod.hydra.sophos.com rejected your message to the following email addresses:

Your message is larger than the size limit for messages. Please make it smaller and try sending it again.
relay-us-east-2.prod.hydra.sophos.com gave this error:
Message size exceeds fixed limit
