    Default [SOLVED] 550 authentication required (in reply to RCPT TO command)

    I get this message when sending mail to some servers.
    Some other servers let mail through.
    Others just drop the connection.

    Any ideas?

    Default

    My server differs from the global settings:

    MTA is: 127.0.0.0/8 10.180.0.0/16
    and Enable DNS Check is off.

    I think he has general send/receive of mail? (I keep mentioning the dns checks-but him and john were working on it last night, and might have specifically set dns checks off?)

    If you're talking about a relay Outgoing SMTP Authentication - Zimbra :: Wiki

    su - zimbra
    postconf
    check your value's of these across the board
    smtpd_use_tls
    smtpd_tls_auth_only
    smtpd_tls_key_file = /opt/zimbra/conf/smtpd.key
    smtpd_tls_cert_file = /opt/zimbra/conf/smtpd.crt

    If you want to get some more output:
    smtp_tls_loglevel
    0 Disable logging of TLS activity.
    1 Log TLS handshake and certificate information. (what you have currently)
    2 Log levels during TLS negotiation.
    3 Log hexadecimal and ASCII dump of TLS negotiation process.
    4 Log hexadecimal and ASCII dump of complete transmission after STARTTLS.
