Does the from address have to exist when sending an email?
Having issues with people receiving my emails when sending from code, and the only thing I can think of that is different is that the from email address does not exist.

No it doesn't, there's lots of reasons why the main may not get delivered. Jeff Attwood has a good article that spells out a lot of the things to look at sending mail through code. | ||||

The from address doesn't have to exist but note that if the sender's domain doesn't exist the message is far more likely to be flagged as spam. | |||

I think it has to exist but doesn't have to be accurate. | |||
