Hi,

I use Microsoft Outlook 2003 on my laptop with wireless internet
access. I have no problems with it at home; mail sent and received
successfully. However, when I use my laptop elsewhere with Wi-Fi, I
experience problems sending mail. (I never have a problem receiving
mail). Sent messages often (not always) get returned to me. The
returned email is marked from 'System Administrator', and the subject
is marked 'Undeliverable', followed by my original subject. My
original message is stripped from the body of the email, but the
message body in the returned email says something like this:

"Your message did not reach some or all of the intended recipients.
The following recipient(s) could not be reached:
' on 1/24/2006 2:13 PM
550 relaying mail to aol.com is not allowed"

I use Adelphia as my email service. I can send emails successfully
through Adelphia's web site, which is what I usually have to resort to
doing once an email gets returned to me. I have not figured out any
rhyme or reason as to which emails get sent back to me. In addition,
lately some emails that I sent took over 4 hours to be received. With
Outlook, I have one email account, incoming mail server (POP3)
mail.adelphia.net. Outgoing mail server (STMP) mail.adelphia.net. Do
I need to set up another account for when I am not at home?

I have Norton Internet Security 2005 enabled.

Thanks in advance for any help!
