Re: Event 1019, 1023, 1036 and POP3

Hi Paul,

Thanks for your time and efforts to the issue.

I am sorry for the delayed response due to weekend. Please understand that
the newsgroups are staffed weekdays by Microsoft Support professionals to
answer your systems and applications questions. Your understanding is
greatly appreciated!

I suggest that you take a look at the following article to get more detail
information about using smart host or DNS to send emails.
http://www.sbslinks.com/DNS_Smarthost.htm

According to the PTR issue, you can contact your ISP to add a valid PTR
record to resolve the issue. As we known, the Comcast and many other major
mail servers (such as AOL) are now blocking mail when they cannot resolve
the sending e-mail server. AOL is doing reverse DNS lookup on the
Exchange/SBS box against the recipient's address of the mail. The AOL.com
mail server requires that a valid reverse DNS record (known as PTR) for all
of your domain's MX records. AOL.com also requires that for every inbound
SMTP connection, the connecting SMTP server must have a valid PTR record
even if an MX record does not exist.

Intelligent Message Filter on the Exchange server to filter spam to protect

Smart host means using the SBCGlobal SMTP server instead of DNS in your
Exchange connector properties.

Steve,
I do have a static IP. But SBCGlobal will not do a reverse lookup on it.
And it doesn't resolve to our mail server but to the SBCGlobal server,
so
we end up with two strikes against us for spam.

Can you expand more on the smart host method. That is a new term to me

Thanks

Paul

Sending via the smart host method usually will workaround the reverse
lookup issue. Even more important would be a static IP if SBCGlobal is
only providing a dynamic IP as that also helps to resolve most spam
filter issues as well as makes the SMTP setup easier in the long run.
Again you're using the POP connector for long term use and it was never
intended to do that.

"Paul Proefrock" <proefrock@xxxxxxxxxxxxx> wrote in message

Steve,
When SMTP is used, you need to have reverse lookup to get past most
spam
filters. Our ISP is SBCGlobal who refuses to manage the account or
provide the reverse. They will release it to us, which then provides
an
entirely new level of complexity and skills, not presently possessed.

I'd love to go to SMTP. Maybe I need to use this as incentive to learn
about Internet IP Address management.

Suggestions on a learning site?

The POP connector was never intended for long term use but more as an
interim service while SMTP was setup. Any reason not to switch to
SMTP?

"Paul Proefrock" <paul@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx> wrote in

We get intermittent errors on our POP3 connection that triggers an
item in our event log. Event ID 1019, 1023 and 1036.

I have researched this and see it is a common problem but have never
found a way to fix it. It seems the errors are thrown if there is a
break or glitch in the POP3 account. The connection still works ok
and
the mail is downloaded without any other problems. I have never had
to
go in and reconnect or rebuild the connection.

Are there any ideas on how to correct this. I have seen it is
considered "benign" but it is kind of annoying to find there in the
daily report. I like a clean *** each morning.

Thanks for any help

Paul P
