I can receive emails but cannot send
If you can receive mail but aren't able to
send this means one thing.....
Your internet provider is blocking you from using anyone's outgoing mail
servers but their own. Many major ISP's are blocking outgoing emails.
The reason they do this is to prevent you from using their internet
connection for spamming purposes. You will still be able to send emails,
but only by using your ISP'S outgoing mail server. Every ISP's outgoing
mail address is different, but for the most part they will be
mail.yourispname.com For example, if you had hosting with AOL.com, their
outgoing mail server would look like this: mail.aol.com If
mail.yourisp.com does not work and you are still unable to send emails,
you will need to call your internet service provider to find out what
their outgoing mail server is.
