I often have clients email zip files to me only to find out that their corporate firewall has stripped the attached file. What is the most straight-forward way to send a compressed file through email and avoid getting your attachment stripped out by over-eager firewalls?
To clarify, I'm not worried about sending files out as I can host them on my own web server for download. I'm looking for a good, simple solution for having clients email files to me.
To clarify further: since I have control over my software running on offline client systems, and I control how the data files are created, I'd still like to explore options of how I might package my data to make it as easy as possible to email specifically. I'd like to avoid requiring my clients to install any additional software or use third party websites on their end.
