Ima li još nešto od teksta? Ovde ne piše razlog zašto nije isporučena poruka, već samo da nije isporučena poruka, a to ništa ne znači.

Probaj sa nekog drugog email naloga.

Na hotmailu pise Undeliverable: Unable to deliver message to the following recipients, due to being unable to connect successfully to the destination mail server. A sa drugih sa kojih sam slao pise:
This message was created automatically by mail delivery software
A message that you sent could not be delivered to one or more of its
recipients. This is a permanent error. The following address(es) failed:
[email protected]
SMTP error from remote mail server after RCPT TO:<[email protected]>:
host mail.minrzs.gov.rs [92.42.255.83]: 550 <[email protected]>, Recipient unknown

Ajde molim Te !!! pokusaj prazan email na ovu adresu:
[email protected]
nije problem ni da Ti posaljem text

Pa sve ti piše - Recipient unknown

Znači, ne postoji adresa [email protected]
Na njihovom sajtu postoji gomila e-mail adresa za kontakt, ali taj "sekretar" se nigde ne pominje.
