173609 - "From" lines mangled in outgoing mail

Status: RESOLVED INCOMPLETE

(MailNews Core :: Networking: SMTP, defect)

Description

[Bill Owens]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.1) Gecko/20020826

Lines beginning with the string "From" are mangled in the send process to begin
with a space.  For instance, if I send a message body that goes like this:

From the beginning to the end
This is a test

it gets sent like this:

 From the beginning to the end
This is a test

Normally this sort of mangling is done only in the storage of messages, not in
their transmission.  Since smtp clients like good ol' "mail(1)" don't do this, I
have to assume that it isn't standard behaviour.

Reproducible: Always

Steps to Reproduce:
1. Open up a mail composition window that will somehow send text/plain mail.
2. Compose an e-mail that contains at least one line beginning with the string
"From", possibly preceded by any number of spaces.  Case matters - "from"
doesn't do it.
3. Watching with an ethernet sniffer, hit 'send'.

Actual Results:  
In the message sent out to the SMTP server, all lines beginning with "From"
(possibly with spaces in front) have an extra space prepended.

Expected Results:  
That extra space should not be added at the front.

I believe that this bug is related to numbers 110389 and 121946.  At any rate,
those two bugs also relate to the handling of "From" lines.

maybe dupe of Bug 121947

Confirmed with Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8b) Gecko/20050302

You can also see this behaviour by sending a message to yourself and then
viewing the message (view source) and checking for the extra space

Version 91 has all new smtp backend code. If you can still reproduce this issue, please file a new bug report https://bugzilla.mozilla.org/enter_bug.cgi?product=MailNews%20Core&component=Networking%3A%20SMTP
