Password Protected signature forms being received as a .dat file

[lbones]

Last several times I have tried to send a password protected signature form to my clients it is being received as a .dat file in lieu of a PDF.  Is anyone else having that issue and if so how do I correct it.

Happy day,

I recall that this was an issue for users with AOL accounts and certain phone-based email clients.  If that's the case, perhaps help them evolve into a more modern platform.  For free.  Because that's what the modern client demands.

The last two clients had a Yahoo and a gmail account.

Hi - 

Could you try the steps here and see if you're still having the issue?
