How do I completely remove a package?

[sspitfire]

Hi. I need to completely remove postfix. I tried:

apt-get remove
apt-get purge
apt-get --purge remove

but I can still see it in dpkg --get-selections and I can start postfix from /etc/init.d/

So how do I remove it completely ?
tnx

Did you removed postfix using sudo apt-get autoremove postfix --purge?

I did but it tried to replace postfix with exim and gives me this error:

~# apt-get autoremove postfix --purge

The following extra packages will be installed:
exim4 exim4-base exim4-config exim4-daemon-light
Suggested packages:

The following packages will be REMOVED:
mailutils* postfix*
The following NEW packages will be installed:
exim4 exim4-base exim4-config exim4-daemon-light
0 upgraded, 4 newly installed, 2 to remove and 0 not upgraded.
Need to get 0 B/2030 kB of archives.
After this operation, 369 kB disk space will be freed.
Do you want to continue [Y/n]?
E: Could not perform immediate configuration on 'exim4-daemon-light'. Please see man 5 apt.conf under APT::Immediate-Configure for details. (2)

So in the end postfix is still not removed.

Not really a response, but a question: why do you want to remove Postfix in the first place?
