No reply email ideas?
 

When using an email for someone to create an account, do you send their info from a noreply@ email address or something else?

Also, with a noreply@ email if you use one, do you just trash them automagically on the server or do something else with them in case some idiot does reply to it?

Any advice on how I should handle account signups and sending the info to the user?

The sending address of your transactional emails should not bounce (even if it's a noreply). This will kill your deliverability.

Idiot users will reply to your transactional emails. Up to you if you want to keep them, send them to a support ticket system, delete them, etc.
