Use Postfix instead of Sendmail?

I have Sendmail installed for relaying web site emails to Google Apps and have been having random problems very often. If I wish to replace it with Postfix, how do I ensure that Sendmail stops permanently and doesn’t initiate on reboot?

Hi @cloudnine Good choice. Simply stop Sendmail and install Postfix, since it’s a drop-in replacement.

sudo service sendmail stop
sudo apt-get install postfix

So unless you’ve made some special calls to sendmail commands, Postfix should take over everything what Sendmail does. You need to re-do the configuration in Postfix, since that is not converted.
