I will start to say that I am cough a MS dev and not a sys admin so please go easy.

I have a server on the cloud that runs Ubuntu 9.10 (Karmic Koala) and is just a mail server. A lost friend of mine set this up for me, all works fine and it has been running for a couple of years.

The server currently has a single mail user setup and has IP filtering turned on.

However I need to make a couple of mods:-

  1. Add new mail users so I can hand out usernames and passwords to a couple of clients
  2. Add new IP addresses to the safe sender list (or whatever you call it)

However I got no idea where to start and could do with a few pointers (tutorials) showing me how I do these two basic tasks.

Can anyone help?

root@smtpauth:/# ps -ef | egrep -i "mail|post|exim"
root      2404     1  0 Apr09 ?        00:00:02 /usr/lib/postfix/master
postfix   2412  2404  0 Apr09 ?        00:00:00 qmgr -l -t fifo -u
root      2413     1  0 Apr09 ?        00:00:01 /usr/sbin/dovecot -c /etc/dovecot/dovecot-postfix.conf
postfix   2471  2404  0 Apr09 ?        00:00:00 tlsmgr -l -t unix -u -c
postfix  32299  2404  0 13:44 ?        00:00:00 pickup -l -t fifo -u -c

edit2 I have found this as an old note

ADD USER

cd /
useradd smtpuser 
passwd smtpuser 
KEY IN PWD

then 

cd /etc/postfix
ls -l
cp main.cf main.cf~working20120504
nano main.cf
CTRL + w type in mynetworks
OR user up down arrows to find mynetworks
add space then IP address
CTRL + x
then press Y
/etc/init.d/postfix reload

So it looks like I first add a user then add IP address to a config setting called mynetworks.

If you can tell me what mail server you are running, I'll be happy to help. If its running, which I'm sure it is, youll see it under

ps -ef

Look for 'mail' 'postfix' 'exim' 'sendmail'

ps -ef | egrep -i "mail|post|exim"

If its postfix, heres a link to ubuntu's howto. https://help.ubuntu.com/community/PostfixBasicSetupHowto

Adding new addresses to the safe sender list, or whatever you mean, will be carried out by the server, your mailboxes will be services by dovecot. https://help.ubuntu.com/community/Dovecot

So now i wonder where the user mail is kept, are your mail users maintained in the operating system? Do you see them in /etc/passwd and are the directories mentioned look like they may be for customers?

  • Hi Sirch, I have managed to find a very old note from an old backup. Thanks for you input you helped me by mentioning the word postfix that I was able to search for. I will accept your answer. – Rippo May 04 '12 at 14:36
