Thank you Tim, I thin we cleared now everything.
Today I have an new Problem an I dont know if I have done anythin wrong or if it is a bug:
If I sent out mails from my ClearOS 6 with a local username like email@example.com
the mail dont leave the host and is sent to the local user alex. Also with an Alias-name firstname.lastname@example.org
I receive it local.
Other names ar working fine and going to my relayhost.
Im using a relayhost with authentication (sasl-password) like in 5.2
Can anyone test if its only my individuell problem or isit a mailrouting-bug?
