Help block send mail in zimbra

[Trantor]

Hello biitc .

Regrettably, it seems that you have a basic security problem with your server which needs to be fixed before we can help you further.
That sort of problem has, unfortunately, nothing to do with either Zimbra or ZeXtras, so we cannot help you with that.
Our advice is to consult with security professional to evaluate your current situation.

If you'll need any more Zimbra or ZeXtras-related advice once your system is clean feel free to ask again

Regards,
Trantor

Hi Trantor,

I used it for the first time, I need to stop it right now,

I don't want all user send mail to "only email". Example: "example@gmail.com"

Help me, please

Hi Biitc,

How if you try to use blacklist email on amavisd.conf.in? just open file /opt/zimbra/conf/amavisd.conf.in with your favorite text editor and add email address that you want block. See the following example :

# soft-blacklisting (positive score)
'sender@example.net' => 3.0,
'.example.net' => 1.0,
'example@gmail.com' => 100.0,

save and restart Amavisd with command zmamavisdctl restart

Hi biitc,

you can just add a new postfix transport file and tell at zimbra to use it:

1) create a file like this:

~$ cat /opt/zimbra/conf/postfix_transport
example@gmail.com	error:Your Access error message
blockedDomain.com	error:Your Access error message

2) Check zimbra local transport setting:

~$ zmlocalconfig postfix_transport_maps
postfix_transport_maps = ldap:/opt/zimbra/conf/ldap-transport.cf

3) Then change the same zimbra local setting to add the new file:

~$ zmlocalconfig -e postfix_transport_maps="hash:/opt/zimbra/conf/postfix_transport,ldap:/opt/zimbra/conf/ldap-transport.cf"

...after 1 or 2 minutes, the zmconfigd component will reconfigure postfix for you
Just take a look at /var/log/zimbra.log to see the changing.


Have a nice day.

Hi, I tried to write this rules but I got errors in zimbra.log:

Jan 22 14:30:05 zmserver postfix/trivial-rewrite[10670]: warning: transport_maps lookup failure
Jan 22 14:30:05 zmserver postfix/trivial-rewrite[10670]: warning: hash:/opt/zimbra/conf/postfix_transport is unavailable. open database /opt/zimbra/conf/postfix_transport.db: No such file or directory


I think needs other step.. right??

Thanks

Opsie! Looks like the guide is missing a command:

After creating the postfix_transport file and after adding the addresses/domains you want to block you need to create the .db file since the type is "hash:"... You can do so by running

postmap /opt/zimbra/conf/postfix_transport

as the Zimbra user.
