OT: Co znamena tento mail.

[Jindroush]

To naprosto zalezi na typu smtp serveru a libovuli administratora.
Ja bych treba noreply akceptoval a presmeroval do dev/null

Obecne snad jen postmaster@ a abuse@ ucty by mely byt nejak aliasovane 
na spravce, aby vas mohl nekdo kontaktovat ohledne potencialnich potizi.
