Hi,
This morning different customers called us having problems with their email. The aren't receiving email anymore.
So i checked some things. f.i. telnet [maildomain] 25. And yes, mail doenst work. The message i get (same at all locations) lost connection at CONNECT. Suddenly i get step further. I can connect but when i enter EHLO me i got the same error.
But when i type HELO me it works. Even when enter EHLO me after HELO me I can send e-mail. So there's the problem.
But how can i resolve this ?
thanks,
sylvester
