Is it really true that if I send a mail with a size of 7.8 MB than it will be bigger when it arrives.
I'm in a discussion with an administrator who claims that if he sends that 7.8 MB mail then the mail size expands with 33% to 10.374 MB?
7.8 MB + 2.574 MB (33% of 7.8MB) = 10.374 MB
We have a 10 MB limit here in the company and this administrator can't send that 7.8 MB mail to us.
I tested it and sent a 9.3MB from my external mailbox to my company mailbox and saw that the size didn't grow bigger.
But why claims a "Messaging specialist" that the size is growing?
