Recently decided to setup a server with ISPConfig, installation went pretty smooth only had a few issues to iron out. Now we are faced a dilemma. We did not setup our server from scratch our datacenter loaded CentOS we picked up from there, so let me say that first and foremost. We used the following guide: http://www.howtoforge.com/perfect-server-centos-6.4-x86_64-apache2-dovecot-ispconfig-3 And followed the comments to work out the issues with Dovecot which now works fine for receiving e-mails. But we cannot send mails at all. We have verified with our datacenter that no ports are blocks. The other issue is we cannot access our ispconfig cp at our hostname, only be IP. Any ideas on what may cause this. Thank you all for any help you can provide.
