I am trying to figure out how to enable basic authentication on an exchange server properly.  I disabled anonymous authentication for the smtp server, and was then unable to authenticate with any of the users in Exchange while testing the server via telnet.

I was logging into the server via telnet and doing the following commands

ehlo
auth login
user@domainname.com
password

it the said authentication unsuccesfull.


Any idea on what I could be doing wrong? I change the settings so that all authenticated users were able to relay for testing purposes, and it still did not work.

Hi,
On exchange you do not have to mke any changes for users to be able to authenticate and send mails, Thats how it is meant to be done, they should be able to send out mail.
But if you are expecting some WebServer etc or some specific client/server (based upon IP) to be able to send out then in SMTP Virtual Server, you got to place that IP in exceptions list.
Let me know
Thanks

Thanks EndureKona for the articles.  I over looked the fact that I needed to use base64 to type in the passwords and usernames.

gupnit-

I am having an issue with a server sending out mail through the Exchange server.  I have another server that sends out email using the SMTP virtual server built into Windows 2003. I have 2 questions regarding this.

first is what server will the email show as coming from?  I want to make sure that the SPF records will be good and that it will show as coming from the exchange server.

second is the exchange server doesnt seem to be accepting mail from this other server that is addressed to people within the domain.  Would this be related to SPF records? (I dont have one set for the plain server, only for Exchange)
