[linux] Postfix a obmedzenie velkosti mailu

[Ing. Jan ONDREJ]

Dalo by sa to ale riesit cez nejaky "policy filter". Postfix ma moznost
definovat externy policy filter, ktory predava tusim informacie ako:
  odosielatel,
  autentifikovany pouzivatel,
  velkost posty

Takze ide len o to, napisat vhodny policy scanner, co nieje az take
zlozite (popripade mozem pridat do sagatora 0.8+). :)

Ziaden klient ale nieje nuteny v SMTP hlavicke posielat aj velkost
spravy, takze je mozne, ze to nebude 100% kompatibilne, ale vpodstate by to
malo fungovat, pretoze ESMTP sa uz takmer vsade pouziva a kde nie,
tak je tusim mozne velkost zapisat aj v SMTP.
