mail size increase with attched file and attachment size
The issue: Mail size with no attachment is about 3,17 KB (3.251 Bytes) Mail with attachment 38,1 MB (38075102 Bytes) where the attached file is only 27,8 MB (27820247 Bytes) Why is mail with attachment this big and is even bigger when the attachment is bigger? I calculated 30 percent increase of the mail size itself from the attachment size. This causes problems with mails sending to an SMTP Server with a size limit from 20 Mb not able to send a 19 Mb file cause the mail itself is even larger. This is only in Thunderbird.

Sending a binary file as a attachment increases its size by a third due to base64 encoding sending two 8-bit characters as three 7-bit ASCII characters.

Can we change it somehow?
You could zip the file to make it smaller. Or if an image reduce the dpi or size to make smaller file.
