I have tried and tried to remove sendmail (using debian) but it seems to not be gone. It is still listening on port 25, and I don't want it to be:
zedsaid:/etc/rc2.d# lsof -i :25 COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME sendmail- 23925 root 3u IPv4 4535835 TCP zedsaid.com:smtp (LISTEN)
I have done apt-get remove sendmail and also manually removed some things, but it won't go away. I need to have postfix listening to port 25 instead, is there a way to manually remove sendmail from listening on port 25?
