Error when trying to send e-mail from the system/reset PW etc.

When trying to reset a PW for a user, I get this error

Cannot send password
System is unable to process your request. Please check: -Recipient Email Address -Your server status

When I try to send a test e-mail I get this error

Send Test Email
Error:The following From address failed: no-reply@comtalk.dk

The recipent email Is OK - and the same is the SMTP server.
in the SMTP log, I do not even see the try to SuiteCRM to send an e-mail
Any advise,

Fixed

I have changed centos SElinux settings to ‘disabled’.

Working now
