Description From 2008-10-12 23:53:48

In Lite 4.0.3, if you press on a "mailto" link in Firefox, an undesirable thing
happens: (only the last handler is available, it's mailx) mailx is not run in a
terminal, so it has no input, and as a result, it even not merely fails, but
rather sends some message (empty? or whatever -- that's not important) without
your consent to send it.

Probably, that's either because the specification

'/usr/bin/mailx --':VT

in /etc/urlview/url_handlers has un unsuitable mode (VT: Launch in the same
terminal) or because the VT mode is not handled correctly in the script (it
shouldn't be started if there is no interactive input).

The latter thing must be fixed: a VT program shouldn't be run with no
interactive input: so either it should forcibly run in an xterm in such case,
or it should simply fail.

As for the first thing, I don't know whether XT would indeed be a better mode
for mailx.

What happens:

$ mailx -v -- imz < /dev/null
No message, no subject; hope that's ok
Mail Delivery Status Report will be mailed to <imz>.

One more possible workaround/solution/enhancement: call mailx in url_handlers
in a forced interactive mode; then it will fail in such cases:

$ mailx -v -I -- imz < /dev/null
mailx: tcgetattr: Inappropriate ioctl for device

But that won't solve the problem of sending mail from Firefox when no other
mailers are available. So, there is still need for some modification, such that
xterm will be used in such cases.

<a href="mailto:imz@example.com">An example link</a> to press in Firefox (which
generates an empty message).

Another way to reproduce: right click, and "Send" in the menu. It generates an
empty message to nowhere. (See postfix logs.)

url_handler-0.3.1-alt1 -> sisyphus:

- url_handler.sh: added "mailto" type autodetection (closes: #24627).
- url_handlers: changed mailx mode to XT (closes: #17538).

  colon-separated lists without necessary full path (closes: #3482).
