Re: Re: HELO не проверяется, либо я чего-то не понимаю

Здравствуйте, Maria Gorbatova!

MG> RFC2821, 4.1.4:
MG> ..
MG> An SMTP server MAY verify that the domain name parameter in the EHLO
MG> command actually corresponds to the IP address of the client.
MG> However, the server MUST NOT refuse to accept a message for this
MG> reason if the verification fails: the information about verification
MG> failure is for logging and tracing only.

В том же RFC:
The domain name given in the EHLO command MUST BE either a primary

      host name (a domain name that resolves to an A RR) or, if the host
      has no name, an address literal as described in section 4.1.1.1.

Так что я за наличие галочки :) Особенно на на MX'овом листнере
