my first question
 

Hello to all-bodies. I am nordie and I should need to know a mail operator service at which I could create my unipersonal e-mail dominion but, please that must be stronger secure. Thanks you anyform

Hi Nordie,

You would be best searching on the web for "secure email providers" or similar.

This is an example of the sort of page you'll find:

Edit: Just a piece of advice. It will be easier in future if you consider giving a more descriptive/meaningful title to your thread rather than "my first question". That way, others will be able to know what your thread is about without having to open it.

I agree with the recommendations that hydrurga has offered to you nordie.

A next concern is that you should evaluate exactly what you mean by secure and how secure is acceptable for your situation.

Lots of good options. We use Zimbra, for one.

I'm a postfix + rmail user, with roundcube when I need/want a GUI. Works pretty well, and since it's my own email server, I can restrict access as much as I want. I can't guarantee it's secure, but it feels pretty good.

At least you know it's more secure than running an evil m$ exchange server. lol
