I’m using javamail to try to receive my inbox mail.

I use a redhat vm where I mounted my mail server there, then on my local machine I connect to roundcube 192.168.137.32/roundcube. and I’m able to send and receive mails there.

Now on my dev vm, i’m trying using javamail api to receive my inbox mails, but I get this error message:

Also this what I use is the roundcube config file :

<?php   $config['db_dsnw'] = 'mysql://roundcube_admin:Passwordxxx@localhost/roundcube';   $config['default_host'] = 'localhost';  $config['support_url'] = '';   $config['des_key'] = 'q4CjrPyqCM5yw4Ca6T2uwc5M';   $config['defautl_port'] = 143; $config['smtp_server'] = 'localhost'; $config['smtp_port'] = 587; $config['smtp_user'] = '%u'; $config['smtp_pass'] = '%p'; $config['smtp_auth_type'] = 'LOGIN';  $config['smtp_debug'] = true; $config['plugins'] = array('virtuser_query');  $config['virtuser_query'] = "SELECT Email FROM postfix_accounts.accounts_table WHERE Email = '%u'"; $config['debug_level'] = 4; $config['sql_debug'] = true; $config['imap_debug'] = true; $config['ldap_debug'] = true; #$config['smtp_debug'] = true; 

Note: I didn’t add any certificate on my redhatvm. I also can ping my redhat vm where the postfix is mounted from my dev vm without any problem

Thanks you a lot in advance.
