what is the exact format i should type to use smtpdiag tool for win 2003

im thinking: smtpdiag sender to recipient

command: smtpdiag mike@dc10001.com mf004d4016@blueyonder.c.uk - but it doesnt work

Watch Question


You missed out an O in the blue yonder address ;o) Suspect that's not the issue though!
Syntax is smtpdiag "sender address" "recipient address". use the quote marks
In fact you shouldn't need quotes, but you do need to be in the directory where smtpdiag is stored within the cmd prompt
ie c:\tools\exchangeTools> smtpdiag senderaddress recipient address (check where smtpdiag is

Not the solution you were looking for? Getting a personalized solution is easy.

no that not the issue, ive double-checked that & I also added the " " " " at the start and end of both sender and receiver addresses.


ive installed smtpdiag and let it install by default.  I was told before that I should just open up cmd and type the above, which still did not work.

I also double-clicked the tool, although it is not where you say and the dos screen just flashes on and off.

i did initially logon as administrator
create user: mike.dc10001.com, gave it temporarily admin privileges
logged off as administrator on server and tested new mike account which is ok
this has all been done after exchange was installed
I did install smtp on administrator account and tried to run same commands as above for mike account, but this did not work.
so l logged onto same server just to test, installed smtp and still nothing.

It won't work if Exchange is not working, like in your other question.


hi tntmax, yeh your right.  just need to create those smtp's on the server via recipient policies once i understand about the smtp on my other questions.

You need to know where you installed it to. Can you navigate to the folder and find it? If so, then you need to bring up a command prompt and CD to that directory. Then you can run smtpdiag. However, if it gives you errors, then that is not the same as it "not working"


just so you know ive asked for a Business account with NTL, who blueyonder also belong to.  between 10-15 days for install and will then have a static IP address.  so can test then.  once port 25 is open although blueyonder said it was.  but I do agree it obviously must be.


hi tntmax,

if you give me a few days i will come back to this question as ive now separated my exchange server and primary dc and currently in the process of reinstalling exchange on a separate server.  i do have though another thread out there regarding getting a static ip address from my provider which i have now.  i havent been able to log back onto this account for some time until today.
