181130 - Using Moziilla with a 3rd Party MAPI Client like Pegasus Mail

Status: VERIFIED DUPLICATE of bug 11459

(SeaMonkey :: General, defect)

Description

User-Agent:       Mozilla/5.0 (Windows; U; Win 9x 4.90; en-US; rv:1.1) Gecko/20020826

I cannot get mozilla to open up the pegasus mail client when clicking on a
mailto link. Nothing happens. Pegasus is the default mail client on this Windows
95a machine. Pegasus was installed to use MAPI.

The following registry keys all are pointing to Pegasus:

HKEY_CLASSES_ROOT\mailto\shell\open\command

HKEY_LOCAL_MACHINE\SOFTWARE\Classes\mailto\shell\open\command

HKEY_LOCAL_MACHINE\SOFTWARE\Clients\Mail\Pegasus
Mail\Protocols\mailto\shell\open\command

Nothing happens when I click on a maito link.

Added user_pref("network.protocol-handler.external.mailto", true); to the
pref.js file, still doesn't work.

I have 2 other browsers on this machine. Standalone Netscape 4.08 which works
via MAPI when I click on a mailto link and Opera 5.11 which also works when I
click a mailto link. The only difference with Opera is that the mail client is
specified in Opera's mail setup.

The standalone version of Netscape 4.08 has the following entries in the pref file:

user_pref("mail.altmail_dll", "navmapi32.dll");
user_pref("mail.use_altmail", true);

The navmapi32.dll file is in the windows\system directory as well as the install
directory. This all works well, clicking a mailto link invokes Pegasus MAPI and
Pegasus is opened to a new message window.

Since this version of Netscape 4.08 was the last standalone browser released by
Netscape and is really a slow dinosaur I really would like to see Mozilla
support this.

Reproducible: Always

Steps to Reproduce:

3.




Some developers of K-Meleon also tried to get Pegasus MAPI to work with a Win95
test machine and couldn't get it to work either. They suggested I issue a bug
report to Mozilla. It looks like mozilla opens the HKCR\mailto key, but doesn't
read any of the values from it.
