Hello!
Lately I've turned Email-to-Case option and found out that there is limitation to attachments sent via Email.

According to http://login.salesforce.com/help/doc/en/limits.htm there is limit to 10mb for attachment in "On-Demand Service".

But every time I send attachment bigger than 7,5 mb I got Mail delivery failure with "The error that the other server returned was: 552 552 Message is too large; 10485760 bytes max"

From what I've read emails grow up while they are sent by 33% so I figured out that this might be the problem.
Could anyone confirm that? If yes what are the "real" limits for attachments?

Btw maybe anyone knows, if there is way to copy/move attachment from email to salesforce attachments in case (excluding that application on appexchange)??

Best regards

Maciej

Edit: I have just noticed, that there is attachment icon next to email in case view but when i opened email i see: "Attachments[0]".
