So now Gmail would not allow me to send a mail with a .zip file as an attachment. When I tried sending a mail with a zipped file attached, it popped up a message that read "Sorry, for security reasons, Gmail does not allow you to send this type of attachment".
Annoying. Isn't it? What's more, it's not just files with .zip extension. Gmail won't let me attach anything with a .tar and an .exe extension :(
Denying attachments to enhance security and curb spamming and virus, somehow doesn't make too much of sense!
