Postfix: Allow sending to raw IP-address?

  • 772

as I want to send mails to another internal server, i need the following address to be valid:

[email protected]

at the moment, postfix gives me the following error:

Mar 26 10:40:52 ludwig postfix/smtpd[11765]: warning: Illegal address syntax from localhost[127.0.0.1] in RCPT command: <[email protected]>

in another forum i saw these two config options, but they doesn't work anyway:

strict_rfc821_envelopes = no
allow_min_user = yes

any advice how i can disable this RFC standard?

thanks!

    Try to add resolve_numeric_domain = yes into main.cf (Postfix 2.3+)

  2. Instead of trying to work around the standards, why not incorporate the standards into your work.

    First of all, as per RFC 5321, recipient@[ip.lit.er.al] is perfectly valid; unquoted, however, it is not.

    Second, if you have postfix boxes that do not have a hostname, something is very wrong - correct this ASAP if you intend to maintain understandable mail services.
