Hi there, I am sending emails using perl modules. When sending them off, on some accounts they are received while other accounts never receive any mail. As I do not receive any mails from HelioNet/HelioHost ("Password forgotten mail", CRON, etc.) on my personal email account, I suppose the error is on your end. Especially @web.de and @gmx.de do not receive mails... They bounce back giving me: "retry time not reached for any host after a long failure period"
