271225 - Lines with "From" in email body - incorrect saving as draft

Status: RESOLVED WORKSFORME

(MailNews Core :: Composition, defect)

Description

[Met - Martin Hassman]

Lines with "^From " are always problematic in applications using mbox format.

This affets also Thunderbird 0.9 and older and Mozilla too.

1) Write *HTML* mail with line "From " (this should be "From" at the begining of
the line and space) - other characters can follow on this line, this is not
neccessary
2) Save it as Draft
3) Open draft for editing

Result:
The line contains ">" character before the From.

Expected result:
The line should be as the original text of the draft.

This affects only HTML e-mails - plain/text mails are handled correctly (by
including, excliding spaces).

In the saved draft is line ">From <br>", which seems correct. So messenger
should probably remove ">" from the "^>From " lines during opening HTML drafts.
I hope this solution is safe, because ">From " lines are saved as "&gt;From <br>".

Attachment: Testcase

Including test case with some "From" lines. Good mailer should handle all of
them correctly - Thunderbird and Mozilla have problem only with the 6th line.

Not quite -- 16th line is also affected.

Nope, not a dupe -- my mistake.

Note that this is only a problem for mail where the draft is saved in a local or 
POP folder; IMAP draft folders are not affected.

Bug 121946, bug 121947, bug 194382, and bug 248726 are all related.

Ooh, you have true. But 16th line is exact copy of the 6th, so no other problem
here 8-)

Tested by first changing settings so drafts are saved to local folders:  Account Settings, Copies & Folders. Format was HTML.

No problem with the 6th line in attachment 166768 [details] anymore. Closing as WFM.

Thunderbird 52.0.1 (32-bit)
Windows 7 64-bit
