I have problems with my freshly installed E2K7 und windows 2003 R2 x64. It is a single server with a hub role installed. I have no edge server installed, but I tried a few smarthosts (Linux, BSD) and some smtp servers on the internet.
I configured the send connector with * for the destination domains. First I received only meaningless errors through that mail queue gui, than I tried "set-sendconnector -ProtocolLoggingLevel:Basic". I got some information about "bad sequence of commands". I sniffed the network and I got this:
220 mail.webpage.t-com.de ESMTP server ready Fri, 6 Jul 2007 15:02:59 +0200
250-AUTH LOGIN PLAIN
250 SIZE 28672000
235 Authentication successful
503 Bad sequence of commands (specify MAIL first)
It looks like exchange12 unlearned smtp, cause there must be "MAIL FROM<firstname.lastname@example.org" prior to "RCPT TO"???
I've tried telnet on port 25 and I could send email, but that was telnet. Our smarthosts send the same smtp-error 503.
What shall I do? Please can you help me a little further.
Let me assure you that Exchange12 RTM does send MAIL FROM: before RCPT TO:. One thing I noticed is suspicious, you write:
Before we released E12, we changed that to:
in order to have more categories of logging in a later version, and basic didn't turn out to be basic anymore. So you are apparently running some prerelease version, and given this basic failure (that should fail any attempt to make it leave campus) I suspect it's not even a pre release.
Also, since you sniffed the network, can you post the products protocol log itself instead? And/Or post the version of the following DLL: Microsoft.Exchange.Transport.dll?
Even if that here is an older thread, I would like to continue, because its 100% the problem we have encountered.
I can't connect (not even one) linux based SMTP Server. The error differs (depend on the target smtp server). This is an example with an (big) german provider.

In my opinion the connector does not wait for an 250 after auth, this then results in an 500 error from the linux server.
We already tried:
Aktualisierungrollup1 für ExchangeServer 7.0
Aktualisierungrollup2 für ExchangeServer 7.0
Aktualisierungrollup3 für ExchangeServer 7.0
Aktualisierungrollup4 für ExchangeServer 7.0
Actually we have installed
Aktualisierungrollup3 für ExchangeServer 7.0
by the way: We can't deinstall "Aktualisierungrollup3 für ExchangeServer 7.0", cause it says that it hasn't been applied to the product ...... But it obviously had added new featuers (surface) to the managment tools (console et al)
We have tried to change the properties of the connector using the command-line tool e.g
IgnoreSTARTTLS cause we thought that this was the problem (support of one provider told us that we are trying to send with ssl).
I looked for thar transport ....dll, where can I find it ?
I did all what I can do, browsing the web and the technical documentation many hours - I lost more than one day with this "problem" - now I don't have any idea ....

Well thanks a lot!! This sounds very traceable. I'll have a look on the driver, cause it is the Intel Pro 1000 --- funny very funny.
In the meantime I replaced the E12 through Exchange 2003, so the users could work, but asap I'll change it again again to E12.
When the server is installed I'll give a review. Thanks sidsup!!
Use Exchange 2007 on VMWare Server 1.0.5 Win 2003 STA x64
got exactly the same problems with sending mails and SMTP Error Code 503 (Bad sequence of commands, or Mail From: first...)
also got it on another server before, then we decided to reinstall it on a virtual machine, it worked for 2-3 months, and now, the same...
VMWare Network drivers also Intel Pro/1000 ...MT
the latest drivers on intel page: Version 13.0 (but there was no Windows 2003 x64 driver version, so i used the Intel(R) Network Connections Software Version 12.4)
AND NOW: the same problem...
didn't work for me
Any problems from exchange 2007 with using network adapters for his SNMP Commands or something like that?
we have a similar problem with exchange server 2007 in a hyperV Machine with server 2003 64 Bit. Exchange is unable to deliver Email over a smarthost. We sniffed the traffic and we saw, that exchange sends the mail from: and rcpt to: message of the smtp protocol in one Packet. After that packet the smarthost gives an error 503 bad sequence of commans.
If we simulate the same communication with telnet and the messages in different packages the communication is ok..
Is there a possibility to tell exchange to send the two messages in different packages?
