Hello everybody,
I am trying to migrate our ASL 6.305 to the newest 7 version. Everything seems to work fine. The only problem are incoming and outgoing emails. We can send mails to web.de, t-online or gmail. For example gmx does not work. I get the following error if I am trying to send an email:
SMTP error from remote mail server after RCPT TO:***@yyyy.de
host mx0.gmx.net [123.456.789.910]: 550-5.7.1 {mx016} Sorry, your helo has been denied. 550 5.7.1 ( GMX - FAQ - Informationen für Administratoren anderer Mailserver )
Does anyone know what´s not correct in our configuration. In the following thread I read something about using smarthost configuration:

Is it a possible solution, perhaps?
We have a static mx-record. If anyone of you needs additional information, please contact me.
Thanks
toette
