Infinite waiting when connecting on SSL port (465)

[vigiraud]

Hi, I'm trying to connect to two different mail servers using the 465 port for SSL, with this command : pius -A -s XXXXXXXX -r ~/.gnupg/mykeyring.gpg -m "address@example.com" -H "smtp.example.com" -P 465 -u "address@example.com".

In both cases, it will ask for my password, and then, whether I typed the correct one or not, it just gets blocked here infinitely :

Welcome to PIUS, the PGP Individual UID Signer.

Please enter your mail server password:

If I type ctrl+C, here is what I get :

I don't have any trouble sending emails with Thunderbird on the same computer with the same network, using these two different mail servers. I'm using pius 3.0.0 , installed using the Arch package manager pacman.
