I am working on a VPS that has cPanel installed and I wanted to install Postfix on it. However I find that cPanel seems to be quite tightly integrated with Exim. I have done a google search but have only found vague statements that says "cPanel does not support postfix" but I haven't found any authoritative sources in this matter.
So my question is, what happens if I disable exim entirely and install postfix instead? Will it break cPanel? Will everything run as normal?
Update with more questions:
Can I leave Exim for cPanel's internal use and use postfix for everything else? If so, what will happen to dovecot?
