Outlook EXPRESS: inability to send email

S

scott

When I am on the wireless network at my university, I
cannot receive OR send email on Outlook Express. When I
am on the wireless network at my place of employment, I
can receive AND send using OE. When I'm on the wireless
network in my home, I can receive but NOT send. Ugh! What
on earth is going on?

The article, "Cannot Send Outgoing Mail", on the
Microsoft website is, of course, currently unavailable. I
suspect this may have something to do with firewalls, but
I don't know much about those. Moreover, as far as I can
tell, the firewalls settings are the same for all of my
connections. Furthermore, every effort I've made to
review the firewall settings for individual connections
has locked up my computer.

Thanks in advance for your help.

Not a lot of information to go on, so I will take the easy way out and say,
turn on logging in Outlook Express (tools | options | maintenance tab)

From there you should be able to determine some of the following with
keeping the following in mind.

Who provides the e-mail services? (ISP, University, Work, .etc) What
network am I connected to when trying to access said mail account? For
example, assume that I want to send/receive e-mail thru my ISP while I'm at
work. Odds are, the corporate gods are not going to let its employees check
personal e-mail (e.g. they will block POP/SMTP at the corporate firewall)
because they provide corporate e-mail services and you should be using
whatever tools they provide.

Another example might be where I want to send/receive mail thru my ISP while
I'm connected to the University. While the University allows both, the ISP
might not let me send mail thru them because I'm not connected to their
network or didn't meet some criteria (e.g. need to authenticate to the SMTP
server or check for mail before sending).

FWIW, I don't think the built-in firewall of Windows XP is killing you.
Outlook Express doesn't open listening ports. However if you have any
antivirus installed that can scan POP3/SMTP mail as it downloaded, I would
disable the scanning of e-mail (keep the file protection on) to rule out any
weird race conditions since the antivirus software acts as a proxy between
Outlook Express and the mail server.

neo,

thanks for the feedback. i don't understand a lot of what
you're saying, but i'll enable "logging" as you suggest
and see if i can figure anything out.

In answer to some of your specific questions, the email
account is provided by my ISP. The network to which I'm
connected at any given point depends on my location as
described in my original post.

Your second example is something I will definitely look
into. I'm assuming I can figure that out via
the "logging" option you mentioned?

with regard to who is letting me do what, the funny thing
is that i have the most freedom (for lack of a better
word) in terms of sending and receiving personal email
via POP3 and SMTP accounts at work.

thanks again.
cheers.

i meant to include in my last post that the message i
receive from outlook when i am attempting to send from
home (where i am now) is as follows:

The connection to the server has failed.
Account: 'mail.MYDOMAIN.net',
Server: 'mail.MYDOMAIN.net', Protocol: SMTP, Port: 25,
Secure(SSL): No, Socket Error: 10060, Error Number:
0x800CCC0E

You need to set your outgoing server to authenticate using the incoming
server' credentials.

the (insert latest virus name here) virus, all mail sent to my personal
account will be deleted without reading.

By the way, 0x800CCC0E just means failed to connect.

Try opening a command (dos) prompt and type:

ping mail.mydomain.net

do you get four good responses or does it come back with host not found?

okay... try this.

1) open a command prompt
2) open mail client
3) start a mail check and immediately go to the command prompt
4) type: netstat
5) press enter key

looking at the output, does any have the name of the mail server with
"SYN_SENT" after it. (The "SYN_SENT" means some device, program, .etc (e.g.
firewall, router, .etc) is blocking the request to connect.)

work with the support staff at mydomain.net to find out what is blocking
access. You should supply them with what IP address you have when you can't
connect and what time you tried. You can get your IP address by opening a
command (dos) prompt and type:

ipconfig /all

You will want to supply them with:

IP Address:
Subnet Mask:
Default Gateway:
DNS Servers:
Primary WINS Server:
Secondary WINS Server:


Outside of that, I will state again that the Windows XP built-in firewall
doesn't block Outlook Express because it doesn't open a listening port.
There are third party desktop firewall (e.g. ZoneAlarm) where you have to
explicit allow the program to connect.
