I have two Macs on one router, both with Air Play checked. When I do an email Send on emclient on Mac #1, using email “T”, that email appears of course in the Sent folder on Mac #1 on email account T. However, that same sent email from Mac #1 and email account T also automatically appears on Mac #2 with emclient and email account “H” on it. How can this be? I can try turning off Air Play on one or both, but does that really work out, if Air Play is essential for SMTP reasons? The further practical problem is that Mac #2, email H, will not authenticate because the email provider thinks I am trying to send from email account H using email account T! So I can’t even send-receive on email H until this is fixed. Need expert help!

Not sure why you need Air Play so i presume you mean Air Sync which syncs the calendar and contacts with a eg: Hotmail, Live, Outlook type account,
As far as sending mail goes “using any single or multiple router with multiple computers goes”, if you send mail on one computer the same sent mail will only show on the second computer “if you have the sane IMAP, Exchange, Office 365 or iCloud account” configured on the second computer.
So if you are getting the same sent mail from the first computer also suddenly showing on the second computer sent folder, then go to “Menu / Accounts” on the second computer and “check if it has the same account setup”.
Also If the second computer is getting the sane Incoming mail that was sent from the first computer “and its a differant mail account setup than the first computer”, then you may have setup and eg: automatic email forwarding in your first mailbox online to go to your second mail account.
