Not able to send a mail via mailclient with dynamic ips
If a user connect with the mailserver via mailclient like outlook or thunderbird he is able to recieve mails but he couldn't send mails. This problem is when a user has dynamic ips. If the user has a fix ip he could sent mails. I've already test smtp with and without smtp. And I've ask in the german ispconfig forum but nobody have an idea. If you need the logs or a test mailaccount please let me know.
