    Until two days ago I could send emails to a specific address at xxxx@spd.gba.gov.ar
    Then I couldnt send to that address anymore.
    Even I cant send to that address from 3 different servers located in different countries and IPs.

    The xxxx@spd.gba.gov.ar is receiving emails from other locations very well, but I cant send to it at any way. I tried 3 different addresses in 3 different servers I have and the same error.
    Seems that some exim.conf parameter is doing mess. Help!!!!!

    All of them same configured gives me the following errors:


    1Hgfiw-000203-Uw == xxxx@spd.gba.gov.ar R=lookuphost T=remote_smtp defer (-45): SMTP error from remote mail server after MAIL FROM:<mail@mydomain.com.ar> SIZE=1898: host relay1.gba.gov.ar [170.155.5.3]: 451 4.1.8 Domain of sender address mail@mydomain.com.ar does not resolve

    Here is the HELO between servers (it happens with all my servers) and why Is detecting the hostname and ip as forged???????????????????????? Dns setup is ok with no erros at dnsreport.

    Check whether an entry for the domain exists in /etc/localdomains or /etc/remotedomains.
