257686 - Unlisted recipient handled as "Prefers Plain" rather than "Unknown"

Status: RESOLVED INVALID

(MailNews Core :: Composition, defect)

Description

[Mike Cowperthwaite]

When composing an HTML message to a single recipient not in the address book, 
the message is converted silently to plain text as if the recipient were listed 
as "prefers plain."  

It should be treated as a recipient who is listed with an "Unknown" type 
preference: Mozilla should put up the askSendHTML prompt.

This behavior exists in Moz 1.5, 1.6, 1.7.2 and 1.8a3-0824, as well as TB 0.7.

I don't want to be asked in the event of composing email to someone not in
address book. I want it assumed to be plain text. My pref is set to "Convert the
message to plain text . . . .". Would what you're asking here impact that? Do
you have your pref so set when the silent conversion takes place?

Comment 1 is right: I neglected to take note of the preference.  

If the preference is to convert without asking, that's what would happen for an 
unlisted recipient, just as for a recipient listed but "unknown."

Mike, as far as I know, unknown receipients are treated as unknown format
preference.
It *does* convert silently to plaintext without asking, if there's no formatting
to speak of. If there's some formattting, it should ask.
INVALID until further info.

I don't understand this.  I tested extensively before filing this bug, but I 
can't reproduce it now.

I'm seeing this behavior again, with TB 1.0+0725 and TB 1.0.5, Win2K.

Steps to reproduce:
1) Set the "Send preference" to "Send as Plain and HTML".
2) Open an HTML compose window.  Address to an entry in the address book that is 
listed as "unknown."
3) Enter plain text with one character bolded.  Send.
4) Examine message in Sent folder
5) Open an HTML compose window.  Address to an entry unlisted in the address 
book.
6) Enter plain text with one character bolded.  Send.
7) Examine message in Sent folder

Actual results:
4) Sent message is in two parts, text/plain and text/html
7) Sent message is only text/plain

Expected results:
7) Sent message is in two parts, text/plain and text/html

Wait, I'm sorry.  I had a plain-text domain configured that I'd forgotten about.
