Send HTML email with mail, mailx, or sendmail?

Question

All..

I am asking this question, and yes it might look like a newbie posting a question without search first, but I have a caveat that I need to be considered before marking this as a repeat or duplicate of similar posted questions!

I have "googled" and searched on stackoverflow, and tried just about every combination of parameters and methods to get an email sent by either mail, mailx, or sendmail (don't care, will even consider other methods), and have the client recognize the email as HTML and properly display the message along with an attachment.

My request is to find a way to send an HTML email AND attach a file at the same time, with a single command.

I am using mail and mailx "12.4 7/29/08", and I can not figure out what version of sendmail. I am using "Linux 2.6.32-504.8.1.el6.x86_64" (RHEL 6.6 Santiago) build of RHEL.

Looking for any of the following?

• How does one find a program that will allow me to send an email with HTML, attach a file and have it be detected my the email client as HTML with an attachment?
• Format a message and its "body" content, and manually encode a file to be attached so that can be sent and have it be detected my the email client as HTML with an attachment?
• Combination of both of the above?

I am stumped. Many of the posts I found have told me there is a large variety of mail and mailx versions and distributions that have different patterns. I am not porting this from machine to machine, and not looking for portable bash script code. However, I like writing clean code that is fairly portable and standard, but that would be like having my pie and eating it too! :-)
