Well you've not made clear how you want to do that. Are you using the 
iPad/iPhone mail app? Are you using a username/password?

You want to send a mail message from what account to what account through what 
machines?

You need to describe this fully on order to know what you're trying to do. From 
whom (email address) via what server and network to whom?

Actually this make little to no difference, it's all an issue of mail client 
settings and what you're doing on the server end.

Well you also need a SMTP server on this local server too. 

And in which case you can use that account to send your mail message.

A DNS network, that given some of your other comments, suggests is improperly 
configured. You can't shoot both horizons or have two different views of a zone 
in the same DNS set up.

Well you need either some local server or a remote server which will most 
always require you AUTH and use ports other than SMTP's port 25 since many, if 
not most, dynamically assigned IP addresses assigned from ISPs won't permit 
port 25 traffic from your network or it will be blocked by mail servers on the 
rest of the Internet that block dynamic ranges. So you may very likely need to 
use a higher port like the submission port, etc. If you have a local server and 
are on a dynamically assigned IP address from your ISP you'll also need to 
smarthost the mail from your local server to a SMTP server at your ISP or 
elsewhere.

Well this isn't really so much a POP account here but that there's an 
associated SMTP user account that you can use.

Well then those accounts that you created must be using cron. This has nothing 
to do with anything regarding your "problem".

Well that's because you're using POP not IMAP. You need to understand the 
difference and choose the one you need for your workflow.

POP works by a client picking up the mail. This isn't what you want. You 
probably want IMAP.

There is no race condition.

Not really. See above. 

Also note this has nothing to do with OS X servers per se, it's a iPad 
configuration issue and mail client account issue. You need a email account 
somewhere and a proper configuration for it.
