you need

SetEnv HTTPS on

in apache config for squirrelmail virtual host.

or more advanced code in nginx and apache config:

========================================================================

nginx config:
=============

proxy_set_header X-Nginx-Scheme $scheme;

# nginx variable $scheme will be 'http' or 'https'.

apache config:
==============

SetEnvIf X-Nginx-Scheme "^https$" HTTPS=on

# Apache environment variable HTTPS will be 'on' or not defined.

PHP code:
=========

$scheme = getenv('HTTPS') && strtolower(getenv('HTTPS')) != 'off'
     ? 'https'
     : 'http';

# PHP variable $scheme will be 'http' or 'https'.

========================================================================

check for HTTPS environment variable already implemented inside 
squirrelmail: function is_ssl_secured_connection() in functions\global.php.

P.S. also you need something like

   proxy_redirect    https://mail.example.com:80/ /;

in nginx config, because squirrelmail can make redirects
to 80 port instead of default for HTTPS, 443 port.
