admin existed before, www-data i added to test
I send the mail over mailgun relay configured in postfix (or with the api in script)
I use mailgun also as postfix relay for the iredmail mailserver
but mailgun is just for a informative log i thought
i also have the problem when i use SES from aws as relay with sub.mydomain.com -> mydomain.com

Re: Sender address rejected from subdomain

Not clear yet.

*) Which domains are hosted on your iRedMail server? Show us output of command "postconf -n" also.
*) Which domains are hosted on MailGun?
*) You send test email on MailGun as user 'www-data@wiki.domain.com'  to 'admin@domain.com' which hosted on iRedMail server?
