Short answer: it isn't.
Long answer: it is _if_
1) You've got a static IP address, and
2) You set up an MX record for the address from which you're sending.
3) Nobody else at your ISP ever does something dumb and get your IP
address range blacklisted.

Many/most e-mail servers will ignore mail sent from dynamic IP
addresses, from IP addresses that don't belong to machines pointed to
by MX records, from IP addresses in blacklisted ranges that contain a
lot of 'bots, and so on.
I used to use qmail (a sendmail replacement) configure to send mail
directly to the destination. It stopped working consistently years
and years ago because of restrictions many servers are placing on
inbound mail.

Yes. You don't need to use your ISP, but you do need to use a "real"
relay server that the rest of the world trusts. It's possible, but
difficult to set one up yourself. It's easier to use Google's (though
there are issues with using arbitrary "from" addresses). You could
also sign up for an account with some other provider that provides
e-mail service (panix.com, et.).
