IMAP object connection parameter. From where to get?

[zgas]

Hello,

I need to get current smtp connection parameters (host, username, password, port) in one plugin. Is it possible?

This should work:
$smtp_server = $rcmail->config->get('smtp_server');
$smtp_port = $rcmail->config->get('smtp_port');
$smtp_user = $rcmail->config->get('smtp_user');
$smtp_pass = $rcmail->config->get('smtp_pass');
$smtp_auth_type = $rcmail->config->get('smtp_auth_type');
