    What have you change recently on your server ? Have you tried to implement some new Postfix restrictions ? Perhaps you could post
    Code:
    su - zimbra
    postconf -n
    zmprov gacf | grep zimbraMtaRestriction
    Obviously remove some of the sensitive information first.

    Well I would suggest rolling back your changes .. I presume you kept a backup of main.cf ? Reason why I say roll back is what is "##ask" in your configuration

    Well what files did you change ? Did you also run some zmprov commands ? You should also consider trimming down some of the RBLs aswell. At least one of them shutdown in December 18, 2006

    i have changed main.cf.Also i have used zmprov once.But i dont remember exactly the command.

    is it not possible to rollback to the previous status?
    The mailserver was working fine last week.But due to blacklisting of my ip i made modifications in main.cf and also enabled the dspam.
    Waiting for your advice...
    Regards

    A rollback is possible if you have a backup ? I presume your mail server has been down since you made all the changes and you have a up to date backup ?

    Would you also please post /opt/zimbra/conf/postfix_recipient_restrictions.cf so we can see what has been added to that aswell.
