This isn't a question about flarum but rather more for those more familiar with using digital ocean. I have a single core 2 gig droplet with a webserver running. I am wondering if that will be enough resources to also run a postfix send only email server for my flarum website and any other websites I run. Or do I need another droplet to run that? Like I said I only need to use the send only portion of Postfix. I just want to make sure it isn't going to use all the resources.
Thanks for the help.
