SBS 2003 Exchange Intermittent pop3 retrieve errors and lost inbound emails from Internet hosted mail site




Recently, we installed a new SBS2003 server with 30 users. We pull email from an internet mailbox via pop3 and send from exchange via smtp. Users connect locally to the server and use outlook to view.

We are not talking about a lot of traffic. We have a dedicated 144kb Internet connection. It appears to be reliable.

We are losing inbound emails.

We are having intermittent errors on the pop3 retreival process. It will work fine for hours and then give a burst of errors for particular users, not all of them. It will then clear up. The event log lists errors 10060 id 1d1022 about it having trouble downloading an email for a particular user. Microsoft has no info on this error. Then it will clear up. The internet account shows that the mailbox is empty and has been recently accessed.

I know that the emails enter the Internet site, I have them copied, as they are recieved to a yahoo.com account (I keep the original). The emails are received and forwarded correctly to the yahoo.com site.

Questions.

Does the email server (hosted internet mail site) delete the email before the pop3 transfer is complete?

Is there a more reliable method of reception?

What other method can I use to pull email from the internet hosted site (Interland) that is more reliable than pop3?

Can I tune the pop3 connector to make it more tolerant?

Can I use smtp to retrieve the emails? Is it more reliable?

All of the event errors listed in the event log have no information available from Microsoft.

Help, my client is in distress on these "lost" emails! I am too!

We have ran across the same problem with the POP3 connector on SBS 2000 & SBS 2003.  The email is downloaded off the POP3 server but the mail never appears in the mailboxes and the POP3 mailbox is empty afterwards.  The mail goes to a black hole.  The only workaround we have ever found is to use GFI MailEssentials, which is a SPAM filter, but has POP2Exchange in it.  Basicly the same as the POP3 connector, works the same.  We have never had a problem with the GFI Pop2Exchange.

Mike,

I will check into it.

Some things that I have tried - deleted and added particular users  and restarted the mail service - it appears to have helped somewhat...

I am still seeing errors.

Thanks for the feedback.

Question : Can I retreive email with smtp? into the exchange accounts?

SMTP can used for email if you ditch the POP3.  You would have to first have to have a static IP address on you Internet connection.  Second, you would need to have your MX record changed to your static IP. Third, you need to config the default receipient policy for your email domain, which is probably done already.  Forth, not necessary, but beneficial these days, is to have a reverse DNS entry for you mail server, prevents alot of NDR's.  You can them add as many email alias's as you want to add to exchange accounts
