I am experiencing some issues with my SMTP server using ISPConfig. On external (not on server) applications (Outlook, ...), SMTP is working fine, but when I try to use SMTP on a web application installed on the same server of the SMTP(CRM System), it's not working.
I'll guess something is misconfigured, that causes that relaying from localhost to 'external' is not possible?
I can send perfectly e-mails to local mailadresses on the server, but sending from local to external domains is a problem..
Any advice would be appreciated.
Thanks
Error when sending to an external domain:
