815571 - Gmail IMAP extensions enabled by default breaks local server synced with offlineimap

Status: RESOLVED DUPLICATE of bug 815087

(Thunderbird :: Untriaged, defect)

Description

[Richard Marko]

Thunderbird v17 is no longer able to access local dovecot server as it tries to use X-GM-MSGID extension.

Looking into code I found       
      // only GMail will have an AllMail folder.
      if (boxFlags & kImapAllMail)
        SetIsGMailServer(true);

@mailnews/imap/src/nsImapIncomingServer.cpp:1187

Weird thing is that AllMail folder is not synced via offlineimap not even available in 'Subscribe...' dialog.

My account settings:
 account name: <user>@gmail.com
 email address: <user>@gmail.com
 server name: localhost

Same issue as bug 815087?

Yes, looks exactly the same - using gmail directly then switching to offlineimap. Setting is_gmail to false resolves the issue. Thanks.
