What have you change recently on your server ? Have you tried to implement some new Postfix restrictions ? Perhaps you could post

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

I changed that line.and after restarting zimbra the line comes again.How can i change it permanently??

[uxbod]

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...

[uxbod]

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.
