HOW TO install a pop3s server

There are two basic options on Debian: courier-pop-ssl and dovecot; the first is older, I prefer the latter program.

% apt-get install dovecot-common dovecot-pop3d
% vi /etc/dovecot/dovecot.conf

Edit configuration and choose:

protocols = pop3 pop3s

Default configuration avoids plain text passwords; to allow it (usually on POP3, i.e. on port 110), insert

disable_plaintext_auth = no

instead of default commented line:

#disable_plaintext_auth = yes

Debian Sarge package does not come with logging; use, for instance:

log_path = /var/log/dovecot.log
info_log_path = /var/log/dovecot-info.log

On a windowzed POP3 client (like Outlook), do not select "Secure Password Authentication", unless you know what you are doing. On the "incoming mail (POP3)", select: "this server requires a secure connection (SSL)"; port selected should be 995 (means POP-3 over SSL).
