limit messages weight

If you send a large attachment to someone,
it may not go through as their incoming attachment size may be smaller.

The “limit message weight” option lets you define a maximum message weight
so that they will be blocked even before uploading them.

The sending of overweight attachments is stopped,
the email gets bounced back immediately to the sender,
with a warning like:

The message you are trying to send exceeds 
the global size limit of (xxxx bytes) of the server, 
reduce the size of the message and attempt to send again.

Alternatively, large attachments can be published online
in your web space and shared via a simple, lightweight link.

The email with the link to the user area contains the following instructions:

your webspace link: (/temp content is deleted after 7 days)
https://username:secretcode@rsXXX.realsender.com/view/
(copy/paste into: https://webspace.realsender.com)
