Sending mail to Exchange Server

alanhr · 10-20-2008, 03:58 AM

Hi,

I have a machine running RHEL 4.7 on which I am setting up a couple of services that can email reports and logs (e.g., cron). My organization uses Microsoft Exchange Server to manage email and I need to be able to send these reports to various email addresses there. The machine currently has sendmail installed and running, but that seems like overkill -- no email will be sent to accounts on this machine, only from them. I guess in a sense what I am looking for is an extremely closed relay. Is there a simpler approach that will accomplish what I need? I'm a newbie to Linux administration but not to Linux itself, so hopefully I just need a nudge in the right direction. Thanks.

I think you still need to have a transport agent like postfix or sendmail running in the background, but then you can use the client of your choice. You can use something like nail, which supports attachments. I've successfully sent messages to my Outlook account at work with very little configuration.
My gmail account is another story. I've tried to configure it per the man page, but:

Code:

<<< 550-5.7.1 [71.126.241.228] The IP you're using to send mail is not authorized
<<< 550-5.7.1 to send email directly to our servers. Please use the SMTP         
<<< 550-5.7.1 relay at your service provider instead. Learn more at              
<<< 550 5.7.1 http://mail.google.com/support/bin/answer.py?answer=10336 11si1238612gxk.10
554 5.0.0 Service unavailable

. There is probably a way to configure nail using a legitimate isp account, but I haven't figured it out yet.

Thanks for the advice. In retrospect, however, I think I probably made my question too complicated. Yesterday another user asked what was essentially my question, but much more directly, and the reply he received is very simple and works perfectly for me.

Thanks again!
