Config 'flushdns?'

Occasionally a friend has an e-mail returned that was sent to me and MSN says
it might be due to the fact I have a firewall installed. To test this
theory, they suggested doing 'start-run-cmd-ok' and then entering IP
config/flushdns/ Is this something safe to do? I've gotten into situations
before trying something that MSN Help has suggested.
 
its safe. It's: ipconfig /flushdns (notice the space)

ipconfig /flushdns
^^^^^^^^^^^^^^^^^

That command is safe. It purges the DNS Resolver cache. It will rebuild.
If it doesn't, you've got some serious issues you need to resolve anyway.
 
The ipconfig /flushdns won't cause any harm but is unlikely to resolve the
problem. Frankly, it sounds like complete nonsense. If there were a dns
problem you would be having more issues than one friend's email. What does
the returned mail show as the reason for delivery failure? Is it only this
one person who has the problem with mail sent to you? Do you have problems
with Internet access and sending email?
 
It's only one person that occasionally has this problem. I don't have any
problems myself sending or receiving, or any other problems. Her error
mesages are 'unable to relay' and 'system does not like recipient.' She uses
Juno for e-mail and internet access. Since it only happens maybe once in a
hundred times I guess I shouldn't be too concerned. Thanks for quick replies.
 
Your welcome. Clearly there's no dns issue. It sounds like an occasional
Juno glitch and, as you note, probably not worth worrying about.

You never can return your friend's e-mail. Only your mail server can do
that and it unlikely that you operate your own mail server but instead
use the mail server provided by your ISP (internet service provider).
Only your ISP's mail server can refuse delivery of your friend's e-mail.
All you can do is send a wholly new message to your friend. Just
because it has some content from your friend's e-mail has nothing to do
with YOU authoring a completely new message to send using your ISP's
mail server.

Your friend needs to provide more information to you or do their own
research for help. The bounced e-mail will have information regarding
why the e-mail was rejected.

From your other post in this thread, it sounds like your friend is
accessing a mail server that is NOT on the network they use to connect
to the Internet; i.e., they are using a mail server that is off-domain
of their ISP. Tell your friend to configure their e-mail client to
authenticate to the mail server.
