Bug#1041638: bugs.debian.org: the b.d.o mail sofware doesn't parse the "To:" header correctly, generating incorrect addresses

[Don Armstrong]

Control: retitle -1 RFC1522 parsing doesn't re-escape commas

Thanks for the report.

It failed the comma and then went through address expansion.

For future me: the test for this should be that:

From: =?UTF-8?B?UHJldcOfZSwgSGlsbWFy?= 

gets round tripped to the same (or uses quotation marks to escape the
comma). [Use a different address in testing.]

Bug#1041638: bugs.debian.org: the b.d.o mail sofware doesn't parse the "To:" header correctly, generating incorrect addresses

[Vincent Lefevre]

Package: bugs.debian.org
Severity: important

For bug 1041631, I replied to a mail, and the headers were:

To: "Preuße, Hilmar" 
Cc: 1041...@bugs.debian.org

with the "To:" encoded as:

To: =?iso-8859-1?Q?Preu=DFe=2C?= Hilmar 

This is correct and can be visible at

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1041631;mbox=yes;msg=15

But in the copy from
lists-bugs=1041...@bendel.debian.org, the "To:" became:

To: =?UTF-8?Q?Preu=C3=9...@buxtehude.debian.org,
?= Hilmar 

which is completely wrong!

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1041631;msg=15
is not correct either:

To: Preuße, Hilmar 

where the quotes (needed due to the unencoded comma) are missing.
