Resolved 552 5.3.4 Error: message file too big

[TargetA]

I sent an email with a 6 to 8mb attachment and got this message. Did the same minutes later using my gmail account and no problem. How do I set size to allow for large attachments, please?

It is not completely clear to me if this error is coming from your Plesk mail server or from a third party mail server that you were sending the message to?

On Plesk's side, you can change the maximum message size under Tools & Settings -> Mail Server Settings -> Settings.

Here is a link to the relevant part of the docs...
