Can not send zip file from mutt !

["shyamk @ eth . net" <shyamk@eth.net>]

I tried sending a zip file as attachment from mutt , but it does
not go . The recipient does see the mail , but not the attachment !
The version of zip I use : Zip 2.3
This is what file FL.zip shows :
Zip archive data

What can the reason for this anomaly be?

Thanks,
Shyam
