Re: GMail IPv6 IMAP Issue, or is it Just Me?

[Arturo Servin <arturo.servin () gmail com>]

        It works to me, a different one by the way:

telnet -6 imap.gmail.com 993
Trying 2607:f8b0:400c:c01::6c...
Connected to gmail-imap.l.google.com.
Escape character is '^]'.
]
^]
telnet> q
Connection closed.

        The same one, works too:

telnet 2607:f8b0:400d:c00::6c 993
Trying 2607:f8b0:400d:c00::6c...
Connected to qa-in-x6c.1e100.net.
Escape character is '^]'.
^]
telnet> q
Connection closed.


Regards,
as
