Nemáte reverzní (PTR) záznam pro IP adresu serveru, ze kterého jsou zprávy rozesílány.

$ host bl10e-9.abchost.cz
bl10e-9.abchost.cz is an alias for web.abchost.cz.
web.abchost.cz has address 195.70.150.5
$ host 195.70.150.5
Host 5.150.70.195.in-addr.arpa not found: 3(NXDOMAIN)

Takze mam prenastavit DNS?

Aha tady jsem to nasel vysvetlene: http://usenet.jyxo.cz/microsoft.public.cs.server/0503/reversni-dns-zaznam.html kdyby se to hodilo nekoomu jinemu.

Osobne si nemyslim, ze vy s tym nieco mozete spravit.

1. Musite nastavit reverzny zaznam. 2. Musite poziadat ISP, aby vam poskytol moznost reverzneho zaznamu. 3. Ci nahodou nie je chyba nie u vas, ale u tych klientov, ktory nemaju reverzny zaznam a preto im to nedoruci... ? Potom by to chcelo prenastavit postfix.

[lnykryn]

Ty klienti jsou uplne mimo takze tim to nebude.

[lnykryn]

Jen mi prijde divny pro nektery dosly a jiny ne.

[MiK[3]Zz]

Mne to divne neprijde, niektore smtp su proste neastavene tak, ze prijimaju maily len od domen, ktorych ip ma reverzny zaznam na tu istu domenu.

Takze vychodisko ako som vravel je spojazdnit reverzne zaznamy a poziadavat ISP, ktory vlastni range IP, aby povolil reverzne zaznamy.

[Luboš Doležel (Doli)]

Pouze některé mailservery vyžadují, aby zdrojový mailserver měl PTR záznam.
