I need to send mails out from an RHES4.x box (which does not have Postfix installed & sendmail is not supposed to be started as it's hardened for security reason). This box is on the same subnet as a Postfix server. So I needed a way to route mails from this RHES4.x box via that Postfix server. My first attempt in using an MUA (a Perl script) from http://www.logix.cz/michal/devel/smtp-cli/ gave no joy. Now, someone has given me another MUA solution which doesn't require me to install any RPM package: Download & compile the tool below http://sourceforge.net/projects/msmtp/files/msmtp/1.4.26/ to get the executable binary on the RHES4.x box & on this box, create .msmtprc file in the home directory of the user that needs to send email (in RHES4.x box) that has the lines: account postfix host smtp.mypostfix_domain.com from joe_smith@mypostfix_domain.com auth on user joe_smith@mypostfix_domain.com password secret Then I can use the following Shell script (with the compiled msmtp to send out mails from the RHES4.x box: { echo -e 'To:some...@theirdomain.com\nMIME-Version: 1.0 (mime-construct 1.9)\nContent-Type: application/octet-stream\nContent-Transfer-Encoding: base64\n\n' cat myattachment.bin | openssl base64 } | msmtp --account=postfix joe_smith will be a dummy email account on the postfix so the password 'secret' will not be so much of a security issue.
