I don't know why there's so many downvotes and patronising "fly swatter" remarks. There is a use case for this.
For example, sharing a photo album with many pictures. Or a mixtape. Or some song lyrics. I can't upload those to the cloud for copyright reasons.
Or if I want to make the transfer while away from Internet e.g. skiing, hiking, waterfall trip, etc. - there's no access to Internet services, so iCloud/Dropbox/Google Drive just won't do.
I can use lighttpd to serve the folder, but then the user has to hold down and "Save to Camera Roll" for each picture separately.
If both phones have Airdrop, then that's fine. But many phones are not iPhones. We could both install a special app for Bluetooth transfers, but we don't have Internet access, remember? So no app store.
There's a Mail client on every phone, however locked-down it is. If I can serve a collection of files over a local network and send those directly, not one at a time, then that would be very useful to me.
I think a mail server is one solution. If you can propose another flyswatter that meets my requirements, go ahead. Otherwise I still want to find a way to code a mail server, and the parent article is helpful for that.
