BTYahoo Mail set up issue

[kap10]

I use the BTyahoo web browser to manage two of my email accounts.  In one I have a problemas follows:

1. Mail comes in to my in box

2. Despite not setting anything up. mail in the inbox is automatically transferred to my Trash folder and unless I catch it in time trashes the messages.  This only happens with one account, My other account has kept mail going back sometime and I decide what to delete and what to keep.

3. How do I set up my account to stop transferring my e mails to trash.

Footenote :As well as accessing both accounts though BTYahoo web browser I also access them both through my mobile.

Thanks for your help

You need to set your mobile to leave messages on the server, otherwise they will disappear as soon as you've downloaded them to the mobile.

Just checked phone and delete mail on server is swithced off.

I have deleted the account from my phone and will see what happens to new mails coming into the BTYahoo online browser.

Yes, it's a good idea to eliminate the mobile. If it still keeps happening, try turning off the spam guard to see if that stops it.
