User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.0; .NET CLR 1.1.4322) Build Identifier: version 2.0.0.6 (20070728) In "Tools | Options | Composition | Send Options | Plain Text Domains", I entered lists.berkeley.edu, which is only one server in our domain - the listserv machine. Then I try to send an html formatted email to myself, donb@berkeley.edu. It is received as text only. When I remove the lists.berkeley.edu spec, and send it again, it is received with proper formatting. I uninstalled all add-ons except the default Talkback, and the problem persisted. Reproducible: Always Steps to Reproduce: 1.In "Tools | Options | Composition | Send Options | Plain Text Domains", add xxxx.YourMailServerDomain 2.Send yourself some red or blue text. 3.Receive it looking black. Actual Results: Email is received without html formatting. Expected Results: Email should be received with html formatting. My listserv server does not handle html coded email.

Confirmed in 2.0.0.16 on a Mac. More specifically, it appears to be accepting a partial match instead of an exact match. If either "test.example.com" or "example.com.test" are set as plain text domains and you write to someone@example.com, it will get sent in plain text. Actually, it's a little worse than that -- a message to someone@ample.com will also get sent in plain text, which is really confusing and unexpected. It should require an exact match (possibly with wildcards). If not, the screen should get updated to reflect the fact that it isn't, because there's nothing there right now to indicate that partial matches are happening.

It was very rare case, I think. Ben Bucksch, is my guess right? If so, bug 647522 is perhaps "mail address in address book with text/html preference=HTML" case.

Indeed, that's precisely the bug, nail on head. This comparison is just wrong. We need to split the string at ",", then compare the right-most part, and only get a hit, if the email address domain string is equal or longer than the pref domain string, not the other way around as now. Ben
(and before string comparison, add a dot before both domains, to avoid matching "@nopaypal.com" when "paypal.com" is configured.)

This fixes it so that the domain must match exactly, or at least end with dot+the domain. So if the recipient is foo@cc.example.com it would match a domain of cc.example.com or example.com, but not ample.com

Adressing review comments, except for the one about plussing the strings. That's not allowed for the external string api.

Comment on attachment 8365709 [details] [diff] [review] proposed fix, v3 Review of attachment 8365709 [details] [diff] [review]: ----------------------------------------------------------------- This looks good. Unfortunately I just thought of a case where both the old and new code will give the wrong answer, but I think it's an obscure enough issue that I'd be OK with filing a new bug and fixing it later: If the user configures domain.example => plaintext, sub.domain.example => HTML, and the user sends mail to user@sub.domain.example, we'll match ".domain.example" in the plaintext check and not bother doing the HTML check, so we'll send user@sub.domain.example the wrong format. ::: mailnews/compose/src/nsMsgCompose.cpp @@ +5168,5 @@ > recipientsStr.Append(recipient.mAddress); > } > > + // Add recipients to the nonHtmlRecipient list if they haven't > + // explicitely allowed it. nittiest of comment nits: s/explicitely/explicitly/

External api trap :/ Apparently this has to be + nsAutoString dotDomain; + dotDomain.Assign(NS_LITERAL_STRING(".")); + dotDomain.Append(domain); Relanded as https://hg.mozilla.org/comm-central/rev/9668ba473b98
.AssignLiteral ?
That should work too. The think I didn't expect was that nsAutoString dotDomain = NS_LITERAL_STRING("."); works find under external api but doesn't compile w/ internal.
