Re: Failed to open IMAP server

[TSUCHIYA Masatoshi <tsuchiya@namazu.org>]

Hi,

I resolved the following problem, caused by my using additional program.
It defines an around advice of open-network-stream() to support SSH
tunneling, and unfortunately the advice discards the 5th argument of
open-network-stream().  I improved the advice to support the 5th
argument, and succeeded connection.
