Problem sending mail with Outlook Express....killing me!

Last Modified: 2013-11-30
I started work for a new client today who have a Windows 2000 Advanced Server with ~10 machines running XP & Win98.  There is no Exchange server installed, so each machine is essentially using e-mail locally.  They are set up using Outlook Express and they use web.com to host their e-mail.  They said to have not been able to send mail, only receive mail.  I set their outgoing mail server to mail.optonline.net which allowed them to send mail but only temporarily.  Within a few hours they were getting the following error:

Your server has unexpectedly terminated the connection. Possible causes for this include server problems, network problems, or a long period of inactivity. Account: 'pop.registeredsite.com', Server: 'mail.optonline.net', Protocol: SMTP, Port: 25, Secure(SSL): No, Socket Error: 10053, Error Number: 0x800CCC0F

I tried to troubleshoot a bit and found that I couldn't telnet mail.optonline.net 25 from the server or any machines but I could telnet fine from my remote machine off the network.  I rebooted the server and router(D-Link SOHO) and was then able to telnet fine and e-mail worked perfectly.  

4 hours later I got a call saying that they were getting the same error and couldn't send mail.  I logged into the server remotely and found that I was no longer able to telnet mail.optonline.net 25.  I rebooted the server twice, and I still can't telnet in.  Only thing different is I'm not able to reboot the router remotely.

Any ideas?  They have Symantec Corporate installed.  I can log in remotely all night but won't have physical access again until tomorrow.

check if the SMTP server requires authenication - many do - and make sure this is enabled if required

If its SBC/AT&T you can call them and request port 25 be unblocked.

Did you check web.com for how they want your Outlook Express configured?  I had a similiar problem with a client using TW as their ISP but godaddy.com was their email host.  I had to use godaddy.com's email settings SMTP/POP for the client's email.  Check that on web.com.


ISP is optimum online.  i still don't have the symantec password from the old sysadmin so I can't check into Norton.  Will report back soon, so far nothing has worked.

If your using Symantec Corporate or Enterprise.
Go to the Server at  C:\Program Files\Symantec\Symantec System Center\Tools and run the iForgot.exe program
If your running 10.0 or higher.  You can specify the username: Symantec and set your own password.


Default symantec password did not work.  Tried the iforgot utility, didn't work.  Keep getting this error:

"The specified user account does not exist"

Tried Symantec, symantec, Administrator, administrator, admin, and any other account names I can think of that the old admin may have used.

Any ideas??
Ok go here:

You will see the user name there:

Whatever is between the user- and the -p is the user name.  Then go to iforgot.exe and put your username and new password and you should be set.

Is it against the rules to just tell him the default password?  I mean, I hate to see him fight with this when some of us know the password.  
He doesn't even have the default username.

What version of Nortons/Symantec are you using?

suthngin- Does that mean if he did, we would be able to provide him with the pwd?
Yea, it's just 'symantec.'

Before we make this into a trouble-shooting session for AV, has the email settings been verified with the provider/host of your email?  Also make sure you aren't using the email RELAY settings for their email client, but the smtp/pop settings.  That is another sometimes overlooked setting.


Thanks for all the responses guys.  It ended up being an issue with the ISP, optonline and the way the old server was setup.  I got the system stable after talking to Optimum.  Thanks !!!
