The web hosting company I use has a KB article suggesting not to implement a mail server. Can you share your opinion on this? Any pros and/or cons would be appreciated. I never really anticipate levels of web traffic that would overload the server. So i dont really see an issue. Is it a security concern? Or high performance constraint?
Currently Ive setup the free Google Mail for business and it sucks. So here are the descriptions from hosting provider:
Sendmail or Postfix not installed on SmartMachine Appliance
Appliance servers are configured with minimal subset of applications to ensure they are fast and no resources are wasted on things that are not used often. To that end no mail subsystem components are installed by default. If you need to get around that default configuration the steps below will enable outbound email functionality. As a general recommendation this should be avoided if possible.
I can tell you i am running Sun Solaris 11, Tomcat, Apache Web Server, mySQL on same machine.
