Setting up mailX with MS Exchange in SUA


In case you want to setup sendmail on SUA and use your MS Exchange to actually receive the mail and process it further; these steps will be handy.

Downloaded and installed SUA on Windows 2003 R2 system.

Configured sendmail.ch with SMARTHOST entry

Note: A sample entry will look like:

#Smart "relay hosty"

DS<ExchangeServer_HostName>

We need to set the setUID for the sendmail binary explicitly

$ cd /usr/sbin chmod 775 sendmail chmod 4775 sendmail

$ chmod 775 sendmail

$ chmod 4775 sendmail

Note: Unless these steps are performed; we will get “Operation not permitted” error.

Error message: "/bin/ksh: /usr/sbin/sendmail: Operation not permitted"

Then send the mail using sendmail

$ mailx -v -s "test" abhisek@<domainname.com>

Hello from SUA
