My issue is not with the yahoo mail app. My issue is with the pre installed mail app. [The one which has the red stamp icon with the "@" symbol in it]
The email in question is my personal domain email. It connects via pop3 and smtp

OK, so it may seem less than intuitive, but you control that setting NOT from within the email client itself, but from within a menu arrived at through the "Settings".
Go to the main home screen, then press the "Menu" button (looks like 3 horizontal lines, bottom left corner of your phone), then select "Settings", and then "Accounts". There, you'll find all the communication accounts you have set up on the phone. Look for the red box with the while "@" sign and tap it. You will be presented with 4 menu options, and one button. The menu options are "General Settings", "Incoming Server", "Outgoing Server", and "Other Settings".
In the "Other Settings" menu you'll have two selections. The first is a drop-down selection to choose how long of a timeframe of emails you wish to keep on the phone. You can choose from "1 Week", "2 Weeks", "1 Month", "2 Months", and "Never delete messages". Directly below the drop-down is a check-box that will allow you to choose whether messages you delete on the phone will also delete them from the email server. This may be where the problem for your phone lies.
Hopefully this will resolve your issues. If not, I suggest you look to third-party email clients that give you much greater control of how email is handled both on the phone and on the server. I personally like K-9 Mail.
Good luck!
