sendmail/fetchmail/mysql

[zcsnewbie]

I would like help understanding part of the install. The documentation explains that ZCS installs MySQL and no other instance of it should be installed. When I install, I do "yum remove sendmail," which removes sendmail, fetchmail and mysql. Then I do "yum install fetchmail," which installs fetchmail and mysql. 1. Why doesn't this create a problem? 2. Is there a way to install fetchmail without installing mysql?

Thank you in advance!

Having MySQL installed isn't a problem nor does have a running version of MySQL, the Zimbra instance uses non-standard port. It's recommended not to run any other software on the Zimbra server for performance reasons.
