HELP....Can't make outgoing emails

[nebel777]

I have a Touch Pro, obviously, and I've had it since the beginning of the year. Since about 3-4 weeks ago I haven't been able to send outgoing emails from my yahoo account, but yet I still receive them....I've tried to delete the account from the phone and then re"install" it with my password and everything. Still not able to make outgoing emails.
It says:
"The message(s) could not be sent. Check that you have network coverage and that your account information is correct. Then try sending again."

WELL I've done this and no progress any HELP PLEASE?

Please feel free to email me or PM me because it is kinda hard to refind my post after I post something on here because of the high volume of posts.
THANKS IN ADVANCE
