Note, I only send Word and image files. Occasionally I send MP3s.
Oh, I thought your 12-year claim was for you both sending and RECEIVING
e-mails laden with attachments (and by omission would means ALL types of
attachments). Did anyone here ever claim that you couldn't reliably
*send* e-mails with attachments (as long as you are within the quotas
established for your e-mail account)? Your mail server accepts whatever
it gets during the DATA command. It doesn't care if that data has been
corrupted. It won't know. It doesn't care. None of that data sent
during DATA has anything to do with routing your e-mail. Your client
send RCPT-TO command to specify the recipients and then sends DATA to
transfer whatever you want as the content of your message (your client's
headers, blank delimiter line, and body). The mail server doesn't care
about what is the data but that's what it going to deliver. When you
hand off a package to the UPS or FedEx, do they actually tear apart your
package to inspect the contents are all what you claimed they would be?
No, they take the entire package and deliver whatever is inside to the
addressee.
Sending is not a problem (outside of the mail session errors between the
client and mail server, like exceeding quotas for max size for an e-mail
- but then you never did get to send that e-mail so e-mail as reliable
file transfer mechanism isn't an issue yet). The focus is on RECEIVING
e-mails with attachments, especially for large-sized e-mails. Your
reliability in sending has nothing to do with the reliability in
reception. I can toss china plates out a 20-story window and they'll be
in pristine condition as they go out the window but they won't be
delivered in that same condition.
Your experience is of sending 15KB to 150KB Word files attached to puny
sized e-mails compared with others that are sending 10MB to 20MB, or
even larger, e-mails. Tiny e-mails have a far greater chance of not
getting truncated, altered (by AV scanners), or having bits corrupted
during transfer than for e-mails that are 600 to 1200 times, or more,
larger in size. The entire e-mail protocol and system was designed for
transferring SMALL messages and that's why you've had such good luck.
It was NOT designed as a file transfer scheme for huge files. You
trying to carry a teaspoonful of water in your cupped hand will work
well. You trying to carry a cupful of water in your two cupped hands
pressed together doesn't work nearly as well and there is far more
chance of spillage so what you deliver isn't what you started with.
