First locate simcontrol file at /var/qmail/control

The default file looked like this:

:clam=yes,spam=yes,spam_hits=10,attach=.mp3:.src:.bat:.pif:.exe

If you want to just stop spam processing for a single user you have to put:

user@domain.com:clam=yes,spam=no,spam_hits=10

in front of existing line, result:

user@domain.com:clam=yes,spam=no,spam_hits=10
:clam=yes,spam=yes,spam_hits=10,attach=.mp3:.src:.bat:.pif:.exe

for an entire domain just put:

domain.com:clam=yes,spam=no,spam_hits=10

Save an run #qmailctl cdb

if you want to modify qmailadmin to check if new password is strong you can do like this:

edit qmailadmin.c and:

add:   #include <ctype.h>

I wrote a function to check if new password contains at least 1 alphachar and 1 digit.

add it before int main(argc,argv)


int check_strong(char *pass_string)
{
    int digit=0;
    int alpha=0;
    int length=strlen(pass_string);
    int i;
    for(i=0;i<length;i++){
       if( digit == 1 && alpha == 1 ) return 1;
       else{
                  if(isdigit(pass_string[i])) digit=1;
                  if(isalpha(pass_string[i])) alpha=1;
       }
    }
    return 0;
}

#!/bin/bash
for x in `find * -maxdepth 0 -type d`;
do
  # Translate Caps to Small letters
  y=$(echo $x | tr ‘[A-Z]’ ‘[a-z]’);

  # check if directory exits
  if [ ! -d $y ]; then
     echo “mv $x $y”
     mv $x $y;
  fi
done

NOTE: -maxdepth 0 is for directories in curent dir. If you want to rename in depth use -depth instead

problem:

make: *** [ezmlm-gate] Error 1
error: Bad exit status from /var/tmp/rpm-tmp.578TXA (%build)

check if you have:

 /usr/lib64/mysql

if not, make a link :

 ln -s /usr/lib/mysql/ /usr/lib64/

 in /usr/lib/mysql/  you must have something like this:

 libmysqlclient.a
 libmysqlclient_r.a
 libmysqlclient_r.so -> libmysqlclient_r.so.16.0.0
 libmysqlclient_r.so.16 -> libmysqlclient_r.so.16.0.0

 libmysqlclient.so.16 -> libmysqlclient.so.16.0.0
 libmysqlclient.so.16.0.0
