I have three online shopping sites that needs to have email servers so my customers and suppliers can contact me in each of my businesses separately. My website is hosted under 1 Linux hosting service but they couldn't agree to what I require. Are there other Linux email servers I can use that fits exactly on what I need?
I suggest you to use this service from Linux. Obviously Linux serves you free and reliably. You want to know about best Linux email server. Here you go-
Your first suggestion is MTA ( mail transfer agent)
You can able to send mail to your clients randomly, basically bit has more expandable features.
You can also download it from this site.
Second suggestion is MUA (mail users agent). Download it from here
Third one is SMTP (simple mail transfer protocol).
