connect to ssl pop

connect to ssl pop

[Leo]

Dear Gnus,

In the following example setting, connecting to the pop server will be
using gnutls-cli. But it seems that openssl is heavily optimized and
provides better performance.

Would it be better to use openssl instead? Or provide a way to use
openssl for connecting to ssl pop?

(setq mail-sources
      '((pop :server "pop.gmail.com"
	     :port 995
	     :user "user"
             :stream ssl
	     :password "pw")))

Thanks,

Dunno, just try it.

I think this can be done by changing the variable

,----[ C-h v tls-program RET ]
| tls-program is a variable defined in `tls.el'.
| Its value is 
| ("gnutls-cli -p %p %h" "gnutls-cli -p %p %h --protocols ssl3" 
|  "openssl s_client -connect %h:%p -no_ssl2")
|
| Documentation:
| List of strings containing commands to start TLS stream to a host.
| Each entry in the list is tried until a connection is successful.  %h
| is replaced with server hostname, %p with port to connect to.  The
| program should read input on stdin and write output to stdout.  Also
| see `tls-success' for what the program should output after successful
| negotiation.
`----

So basically

(setq tls-program '("openssl s_client -connect %h:%p -no_ssl2"
                    "gnutls-cli -p %p %h"
                    "gnutls-cli -p %p %h --protocols ssl3"))

should do the trick.

Bye,
Tassilo
