Trouble Postfix ClamSMTP - Help


Please now i troubleshooting 2 days about my problem with ClamSmtp

and "Postfix" after write ClamAV_Mailinglist the people there are not

helping and im standing still.

possiblities to release a mail

Hello Together

I ask me if are possible to view on console with postfix command witch
mail's are holding back, Status mailtraffic, and so on not mail.log about
different reasons - blacklisted, spam, or score - and to release this mail
for resend a blacklisted mail.

In the meantime I do this steps with ASSP but I see postfix are so stable I
don't think that no possibilities will exist. And I don't will play with 2
or 3 tools if this possibilities with Postfix exist.

Please kindly let my view and understand the aspect from us thanx for
discuss this possible aspect.

Generate passw with Postfixadmin to add mysql ?


My setup running with Postfix+Dovecot+Roundcube+Mysql

Now I need to add the Password function to roundcube and are available now
with the Passwd plugin, but I need to know

with what hash I need to do this? How will postfixadmin generate the
passwort to add mysql db.

In the meantime I have found the right query but, the password don't accect.
I think i will use the wrong "hash"

'UPDATE `postfixadmin`.`mailbox` SET `password` = MD5('123456789A!') WHERE
`mailbox`.`username` = ' ... at domain dot dtl'';

Thanks for any help
