Already checked the firewall rulesets before. Also no SELinux errors.
even more strange - today around 10:00 o'clock the sendmail started to
work normal until 16:00 o'clock. (with nothing changed since sunday 22:00)
My feelings tell me that the reason might be some strange 'ill-broken'
firewall network stack or some weird netwok communication issues (like
the 'fun' with the ECN-flag some years ago)
I'm tomorrow 'on-site'......
