How to send HTML file using mailx?

Question

Friends,

os : linux

script : ksh

logfile: repot.html

mail : mailx

I'm trying to send HTML file as attachment via ksh script -> mailx command.

I can easily send text file as attachment but as soon as I change file to html, mailx doesn't recognize file and send email with html tags. I tried using uuencode, cat mailhtml etc.. various syntax which I got from internet but somehow nothing works.

I tried attaching html file manually to email and test whether my email client is having problem, but no attachment did sent/receive without any error.

I'm using below syntax, could somebody look and see what I'm missing? $report is a variable which stores html file name.

"
(cat mailhtml; uuencode report.html) | mailx -s "Monthly Report" manager@gmail.com < $report
"

Below works sending normal text logfile

mailx -s "Monthly Report" manager@gmail.com < $report

Thank you for looking into this and hopefully this can be achieved via mailx.
