In Squirrelmail, you can install a plugin html_mail, that allows you to compose html-formatted email.
This plugin functions with Firefox and Internet Explorer; it doesn’t function in Google Chrome.
In CentOS 5 with PHP5.1, I could copy and paste html-formatted text with complicated html (tables, css, etc) from a text editor into the the html-formatting pane of squirrelmail, and the message would be delivered as html-formatted to the recipients.
In CentOS 6, with PHP5.3, using Squirrelmail with the html_mail plugin, copying html-formatted text from a text editor into the html-window in Squirrelmail, the delivered email only shows the header information.
Using pine, I see that there is an attachment, viewing the attachment, I
see the original html code that was composed in a text editor.
Viewing this same received email in a web-based client (Gmail or Squirrelmail), all of html-formatting disappears.
Any suggestions on how to troubleshoot and resolve this?
