Summary0001987: Blank page with some kind of mails (_processCommandParserException)
Description

Some of our users have a blank page when going to the webmail. I have the following errors in sogo.log:

[NGImap4Client]> ERROR(-[NGImap4Client _processCommandParserException:]): catched IMAP4 parser exception NGImap4ParserException: unsupported fetch key: ("\m@yahoo.fr\"

Cf the (hopefully) obfuscated message as attachement

Additional Information

Receivers in the "To" header are of the form :
"\"xxx.yyyy@u-p8.fr\"" <p.e@u-p8.fr>

There is no more problem when I change the above to the following (without \"):

"xxx.yyyy@u-p8.fr"

TagsNo tags attached.

As we encounter others problems with the parser we created a SPGo test instance with ImapDebugEnabled=YES.

I will post here any findings we may have.

I deleted my previous note as it was out of purpose. Also please disregard the 'sope.patch" uploeaded file as it is non-sense...

1 =======
On server headers for the culprit mail is the following:
"ch >> \"ch.x\"" <ch.x@univ-xxx.fr>

2 =======
With Imap deugging enabled SOGo log shows that response to the fetch command is :
("ch >> \ch.x\" NIL "ch.x" "univ-xxx.fr")

3 ========
So it seems

3.1) that our imap server translates a legit SMTP quoted string ("ch >> \"ch.x\"") in a strange one ("ch >> \ch.x\").

3.2) That SOGo is unable to parse the response string "ch >> \ch.x\"

However "ch >> \ch.x\" seems a legit quoted string to me as the double backslashes should translate to a single one ("\" ---> "\")

That mail works for me when I test it using Cyrus IMAP Server.

What IMAP server (and version) are you using?
