Running Smartermail Pro 15.7 and everything works fine normally, SMTP, IMAP, POP etc however if we reboot the machine, then none of the services start properly, looks like they are not binding correctly. Manually stopping and restarting each service in the web interface under Manage / Services fixes the issue.
SMTP log shows this after the reboot.
