I think that the heirloom-mailx version can do all these things since it
supports every mail protocol I can think of.
I'm going to investigate this since I rather like the interface and often end
up wanting to edit email by sshing into a remote machine and ed-like
interfaces just work better over slow connections in my opinion.

Yeah I can see that being quite nice;
though you could just use the mailcap mechanism to do this of course.

I guess I'm just a litle worried about bloat as the browsing side of edbrowse
gets progressively larger in order to keep up with the modern internet.
In addition, there are many features we simply don't have in edbrowse,
I'm not sure exactly what the mail support is,
but for vague parity with modern clients we really need:
imap (with imaps and starttls support),
pop3 (with ssl and tls support),
mbox and maildir support (for local mail),
support for pgp (and for some people s/mime support as well),
Correct threading header support (currently it doesn't work correctly, at least from what I can see in the mail headers in emails I receive from you),
Mailcap support of some kind (potentially our plugin system may be able to do
this but it should probably be integrated),
Probably a bunch of other stuff I've never used.

I'm not saying we can't do this in edbrowse, but I wonder if it's time for an edmail program?

If we modularise the buffer and command parsing interface we could have an ed
suite, with edmail, edbrowse, edtext and (if you want) eddb and edspread.
This would make things quite a lot nicer to work on I suspect,
whilst also making adding new programs (e.g. edspread) that much easier.
There are also other projects where I'd quite like the buffer and command
parsing (and readline) stuff from edbrowse.
A hex editor would be one which would be quite nice to investigate.

Cheers,
Adam.
