I've read the tutorial posted by MountainX (Setup DKIM (DomainKeys) for Ubuntu, Postfix and Mailman), but I can't figure out how to apply these steps if I want to host and send e-mails for several domains. Does anybody have a clue?
I'm attempting to get postfix running on my server but keep getting the following error in my /var/log/mail.log:
postfix/master[5041]: fatal: bind 0.0.0.0 port 25: Address already in use
I did some searching and found this excellent answer by Oli (regarding this very question) in which it's recommended that I basically rid my server of sendmail packages to avoid conflicts, then reinstall postfix, which will in turn install its own brand of sendmail. Unfortuantely it didn't quite solve the problem (see below for how).
I followed the instructions and ran the following check, to which I received an encouraging response:
$ dpkg -S `which sendmail`
postfix: /usr/sbin/sendmail
However when I started postfix again, I got the same error.
As per Oli's contingency, I looked for the process that was hogging port 25 with the following:
$ sudo netstat -pel | grep smtp
tcp 0 0 localhost.localdom:smtp *:* LISTEN root
35704126 27626/sendmail: MTA
But here's where it got confusing: I then looked for the process 27626 but was then told:
dpkg-query: no path found matching pattern 27626
connections.
I pulled up htop and was able to find the above PID associated with the following command:
sendmail:MTA: accepting connections
I then tried to kill the process with both killall sendmail and killall 27626 and kept getting no process found.
The problem is (besides the obvious) I don't know how to interpret these findings. I scrubbed the server of sendmail, so I can only assume that postfix's own version of sendmail is hijacking the port? I don't even know if that makes sense.
Anyway, if anyone could set me straight on this or at least give some interesting diagnostics questions, I'd appreciate it.
In case it's useful, I'm using virtualmin on the server to manage a few different domains and am also running wordpress.
Many thanks in advance!

I know this has been asked a hundred times. But I've done a lot of Google searching without success. My question: I want to log every activity of my postfix server. Neither the default file /var/log/mail nor any other concerning mail or postfix exists.
- What's the exact string to put into the configuration file
/etc/postfx/main.cfto enable logging? - Where can i see which configuration file postfix uses? (according to my hint below)
Thanks for your answers.
Hint: I use postfix together with dovecot. I installed meta package some months ago.

I'm running Ubuntu 12.04 with Postfix and Mailman. I want to set up DKIM. DomainKeys Identified Mail, or DKIM, is the successor to Yahoo's "DomainKeys". It incorporates Cisco's Identified Mail.
What are the steps for setting this up?
Is opendkim recommended?
The only reference I have is HowToForge, but I prefer to get help here (even if it is just a confirmation of the steps at that link). Actually, I think the info at HowToForge is outdated because it mentions dkim-filter instead of opendkim.
I have a couple of cron jobs that sometimes produce error output and would like to get a notification in my "real" email account, since I don't use my user's mailbox in my Ubuntu laptop, but cron (or is it postfix maybe) keeps trying to email the local root account.
I know I can add the MAILTO variable to the crontab:
ricardo@ricardo-laptop:~$ sudo crontab -l
[email protected]
# m h dom mon dow command
*/5 * * * * /home/ricardo/mrtg/cfg/run.sh
But it doesn't seem to pay any attention to it
I also tried adding my email to the /etc/aliases file and running newaliases
ricardo@ricardo-laptop:~$ cat /etc/aliases
# See man 5 aliases for format
postmaster: root
root: [email protected]
ricardo: [email protected]
still, whenever cron wants to send an email it's still sending it to [email protected]:
ricardo@ricardo-laptop:/var/log$ tail mail.log

Any suggestions? I'm running Ubuntu 10.04, with everything up-to-date
