Outlook 2003 stopped sending emails

I've been using Outlook 2003 for almost a year without problems.  All of a sudden, about two weeks ago, it stopped sending emails.  They stay in the outbox and never leave.  I have no trouble receiving emails from my three different ISPs/Accounts, but I can't send or reply.
I've checked all my settings and they've not changed.  The incoming and outgoing server info is correct for all of my accounts.  When I click "Test Account Settings" I get these error messages:
"(0x80042109)"
"The specified server was found but there was no response from the server.  Please verify that the Port and SSL information is correct."
"Outlook could not connect to the outgoing mail server (SMTP).  The problem could be the server name or the port or your server may not support SSL."
I would agree with that diagnosis if it were only one server, but it is true of all of my accounts with different ISPs.  The only thing I did differently recently was dial up through NetZero on a very slow connection, but I've done that before and have not had problems.  I usually use a wireless cable connection.
I've tried finding an answer on the net and at Microsoft, but no luck.

Are you sure your ISP has not stopped blocking e-mail from outside servers.  For example, some ISPs such as Frontier will prevent sending e-mails usig SMTP unless it is going through their mail servers....but you can still recive mail.  Check with your ISP and make sure they haven't changed this.

Hi ljschwartz,

Have you authenticated outgoing server and checked if that would help

open outlook
Tools --> email accounts --> view or change existing email account
click on the account and press change and then More settings
go to outgoing server tab
and check " my outgoing server requires authentication"

I will call my ISP, Optonline, tomorrow.  I don't think they changed their policy in the last few weeks, but I'll check it out.

All of my accounts have the authentication box checked, and have always worked.  Those settings have not changed.

No new popup blockers.  I use Spybot S&D and Ad-Aware to clean spy/adware.  Cleared my temp Internet files, but I do that often.  MTU was set to AUTO so I tried Manual/1492.  Still no luck.  Help!

Yes, and you were right.  Optonline started blocking Port 25 two weeks ago, but never sent out emails to warn us.  They posted it on their website.  Can you believe it?  It cost me three days of frustration and agravation.  You get the points!

Now my question is:
Since I have to change my outgoing SMTP server name to "mail.optonline.net" when I'm at home, is there a way that I can create a separate profile in Outlook so that I don't have to keep changing my five email accounts when I'm working away from home?

None of these things have worked for me for the original problem.  Any other solutions?  I've contacted my ISP and changed all my setting to every conceivable possibility..nothing works.  I can't send email.  
Thanks,
Kristin
