SBS 2003 Smtp connection errors. Odd issue.

[GARETT - TVGTECH]

Setup:

SBS 2003 all updated.
Running for 3 years just fine.
MAC/entourage desktops connect via exchange and POP(on LAN - some Mac's are
checking more than 1 accont)
Windows XP/outlook - connect via exchange and POP(same as above)
Smarthost is hosted spam solutions(outbound.exchangedefender.com)

PROBLEM:
Suddenly, the POP and IMAP connectors (on entourage and outlooks) cannot
send email out.
All POP and IMAP can send out just fine. No errors.

Via exchange sends out just fine for mac and XP. But POP and IMAP accounts
fail when sending out throught the sbs box.

Where does this happen?
This happens with LAN desktop(all mac/XP) POP and IMAP connections, AND all
external users POP'ing and IMAP'ing

Testing:
We can telnet within the LAN from any desktop to sbs 2003. COnnecting.
We can telent from outside and connect to the sbs 2003.
Firewall is sonicwall with all sbs ports open.
Nothing has changed on the desktops.
Nothing else has been installed on the server.
Don't know if any updates on sbs has caused this.

ERROR when connecting POP or IMAP via the SMTP connector:

sending reported error (0x800ccc0f) the connection to the server was
interrupted. If this problem continues, contact your server administrator or
ISP provider.

Cannot find alot info on solving this.

Any help would be really helpful in this headache of an issue!!
thanks All.

Hey Russ thanks for responding.

the relay is set correct for the local lan ip and 127 ip like yours.

I am thinking it has something to do with security or cert? but nothing has
changed since the sudden cut over.

What can i check for security access?
Rebuild the smtp?
I have loggin but doesnt show much of diagnoisis value.

Thanks.

Hello,

Thanks for your post and Russ's input.

You may experience one or more of the following symptoms, when you send email using POP3 settings in Outlook /Outlook Express:

o Cannot send e-mail
o Cannot receive e-mail
o Not receiving all e-mail
o Can send e-mail but cannot receive
o Can receive but cannot send e-mail
o 0x800CCC0D CANT_FIND_HOST
o 0x800CCC0E FAILED_TO_CONNECT
o 0x800CCC0F CONNECTION_DROPPED
o 0x800CCC19 TIMEOUT
o 0x800CCC90 POP3_RESPONSE_ERROR

These error messages may occur if Microsoft Outlook or Microsoft Outlook Express cannot establish a connection with your e-mail server. These error messages are frequently caused by one of the
following:

o You are not connected to the Internet or a network, or your mail server is temporarily unavailable.
o Your account settings are incorrect.
o Your user profile in Outlook is damaged.
o An e-mail item on your POP3 server is damaged.
o The configuration of your AV software is incorrect.
o Outlook Express was removed from the computer or the installation is damaged.
o The configuration of your personal firewall software is incorrect.

To try to resolve this issue, please follow the checklist in KB 813514 and KB 935400:

It takes much longer than expected to download an e-mail message from a POP3 server in Outlook 2007
