iPhone Mail, Send only account I have an account on dreamhost that autoforwards everything on to my GMail. This is fine as it all gets pulled into my phone, but if I try to reply on my iPhone, it shows the google address, not the fancy forwarded address.

To fix this I attempted to add the forwarded account via IMAP to my phone, fixing the problem, and introducing a second. Now I have duplicates of emails one for GMail and one for the original account. What'smore, spam sent to the fancy email is not being filtered, so I'm getting both duplicates of normal emails, and unfiltered spam.

What I'd like is to set my iPhone so it can send from that account, but either does not check for emails, or cannot check for emails.

In the past I've set my phone up to use the 'from' trick, which has almost worked ( users can still tell it's not quite from that address though it gives the illusion ), and the instructions fail when applied to iOS5 ( impending death of the trick? )
I have found the solution!

I set up a second email account on my server with an obscure name, then, I changed the POP/IMAP settings to use that account for receiving, and left the send/SMTP details unchanged.

This now gives me the desired behaviour. It also gives me a receive only account ( which could also be desirable ).

If you are on iOS4 or below, you can also refer to Hand-E-Food's answer. My instructions will work for iOS5 ( due to the extra checks iOS5 makes to verify what you've entered )
