Hello,

I have Windows server  SBS 2003 with exchange server 2003.

Sometimes, i do not receive e-mails from certain domains or cannot send mails to certain domains.

I can receive e-mails from yahoo, but sometime i cant. The sender receives this error:
Connected to XXX.XXX.XXX.XXX but connection died. Possible duplicate! (#4.4.2)
> I'm not going to try again; this message has been in the queue too long.

I did some tests using gmail, yahoo, hotmail and i can receive mails from my accounts.

I am not listed on any blacklist on spamhaus.org.

My website is hosted at bluehost: domain.com, but all my mails are redirected here at mail.domain.com

I receive at least 1 notification a day and i cannot find the cause of this.

Blacklisting wouldn't affect inbound email, only outbound.
What is between Exchange and the internet? Is it just Yahoo that is generating that error?

This 4.4.2 error is only from yahoo.

There is my Firewall --> switch --> mail-server

If it is only happening with Yahoo then it may not be your problem. I have seen an identical error posted elsewhere in the last week or so, that was mentioning a SonicWall firewall which may well be the cause.

The NDR isn't an Exchange message, so it is being generated elsewhere.

thats what i thought, but I also receive exchange error codes on a weekly basis.  I looked up the error codes:
5.5.0 and 4.4.7.   I am more worried aboty the errior 4.4.7 :
 Could not deliver the message in the time limit specified. Please retry or contact your administrator <"mydomain.com" #4.4.7>"

Error codes on their own are close to useless. You have to look at the text in the NDR for the cause of the problem. Connection timeouts can have any number of problems, many of them outside of your control.
Firewalls are a common cause, scanning the SMTP traffic.

Good Day Simon, I went to Dnsstuff,  and I had this warning when  completing a report:

WARNING: One or more of your mailservers is claiming to be a host other than what it really is (the SMTP greeting should be a 3-digit code, followed by a space or a dash, then the host name). If your mailserver sends out E-mail using this domain in its EHLO or HELO, your E-mail might get blocked by anti-spam software. This is also a technical violation of RFC821 4.3 (and RFC2821 4.3.1). Note that the hostname given in the SMTP greeting should have an A record pointing back to the same server. Note that this one test may use a cached DNS record.

mail.domain.com claims to be invalid hostname '******************************************************************************************************************': <br />   220 **************************************************************************************************** <br />


I think it might be related to my problem.

That looks like a PIX.
You need to disable the FIXUP SMTP in the PIX configuration.
