I saw that when I send an email with some attachments (let say a 5MB zip file), Zimbra show me a mail size of 7MB ?
What are thoses 2 MB ? I thought it was a bug with outlook, but trying to send the mail within Zimbra is the same.
Is is just a display bug, or really, each mail I send is increased by "I don't know what" ?
Running Zimbra 7.2 64Bits on Ubuntu 10.04..
