I'm not sure what 22 lines has got to do with anything, but open your mail program, go into it's settings, and check off make default mail client.
This will work with installed email clients. I'm not sure how to do it if it's web based email such as yahoo or gmail.
Hai, this all is done. Email client is OutLook Express. properly linked to ie. when clicked, all mail are opening,nexcept those mails which are having more than 22 lines in the message. that is if the lenght of the message is greater than 22 line. then only this problem.
