able to forward emails but not send new ones

[Matt]

Hello,

I'm kind of experimenting the same problems.
I have 3 email account configured in outlook , two with my isp
(e-mail address removed) and (e-mail address removed) and one with hotmail
(e-mail address removed)

I'm having a weird problem : I'm able to receive all my emails, I'm also
able to send email via (e-mail address removed) and (e-mail address removed) but
not via (e-mail address removed).

I did check the server settings and they are fine , same as
(e-mail address removed) but with a different user name and password. but pop
and smtp are the same.

I did delete the account and recreated it but no luck .

The weirdest thing is that I will be able to forward any email in my inbox
from the (e-mail address removed) but not send new emails from this account.

Anyone can help me ??

I'm not getting any error message either and the message are going in the
sent items but the recepient never gets them...
