OT: Co znamena tento mail.

[Martin Hanek]

Díky, ono mě trklo, tím že visel ve frontě na mail serveru. A visel tam 
proto, že "noreply" nebyl nastavený. Asi jsem nad tím moc přemýšlel.
Přidám otázku: Které účty by měl mail server akceptovat, mám na mysli 
třeba: admin, noreply, mailer-daemon apod. Je to někde popsané?
