Modifying mail:postfix:mynetworks with serveradmin

Hello,

I'm trying to open the relaying without SMTP authentification on my server (10.8.2) for another computer (IP based authentification)

I googled a lot, and I found a lot examples, but when I do the command I get always an error.

After reading http://developer.apple.com/library/mac/#documentation/Darwin/Reference/ManPages/ man8/serveradmin.8.html

I tough I had to to this command

sudo serveradmin settings mail:postfix:mynetworks = create

But I get this:

2012-11-22 14:45:10.041 serveradmin[57534:a07] -[__NSCFString count]: unrecognized selector sent to instance 0x7f8d51003910

2012-11-22 14:45:10.042 serveradmin[57534:a07] Exception in doCommand for module servermgr_mail on thread 0x7f8d5040c510: -[__NSCFString count]: unrecognized selector sent to instance 0x7f8d51003910

2012-11-22 14:45:10.042 serveradmin[57534:a07] --request was {

command = writeSettings;

configuration = {

postfix = {

mynetworks = create;

};

};

}

The I made a lot of try:

FIRST TRY

Found here http://unflyingobject.com/blog/posts/707 :

cat - | sudo serveradmin settings

mail:postfix:mynetworks = "127.0.0.0/8"

mail:postfix:mynetworks = "193.4x.xxx.xxx"

ctrl-d

I get this error:

012-11-22 14:29:15.259 serveradmin[57105:707] -[__NSCFString count]: unrecognized selector sent to instance 0x7ff9c18034e0

2012-11-22 14:29:15.260 serveradmin[57105:707] Exception in doCommand for module servermgr_mail on thread 0x7ff9c0c0c4a0: -[__NSCFString count]: unrecognized selector sent to instance 0x7ff9c18034e0

2012-11-22 14:29:15.260 serveradmin[57105:707] --request was {

command = writeSettings;

configuration = {

postfix = {

mynetworks = "193.4x.xxx.xxx";

};

};

}

SECOND TRY

sudo serveradmin settings mail:postfix:mynetworks = "193.4x.xxx.xxx"

I get the same error message (except the thread ID)

THIRD TRY

sudo serveradmin settings mail:postfix:mynetworks:_array_index = "193.4x.xxx.xxx"

I get this:

Can't have _array_id or _array_index as the last element of a key

for key: "mail:postfix:mynetworks:_array_index"

FOURTH TRY

sudo serveradmin settings mail:postfix:mynetworks:1 = "193.4x.xxx.xxx"

2012-11-22 14:42:03.321 serveradmin[57493:a07] servermgr_mail: postconf write error: /usr/sbin/postconf: fatal: -e or -# accepts no multi-line input

mail:postfix:mynetworks = _empty_array

SIXTH TRY

Found this https://discussions.apple.com/thread/308775

But in my cases I did not works ...

I made a lot of others combination withiut any success ... I'm lost ;-(

Any help, would be greatlty appreciated !
