Le site netaddress.com est-il sûr ?

I've used them for decades. The calendar etc. have worked, but I rely on Thunderbird for that. Two main things I appreciate about them. I wanted to change my email and was prepared to get a new subscription and spend a couple months changing my email on file as things came in. They offered to rename my current account so that I didn't need to change all my aliases (see next) and let me use a dummy acct with my old name while I changed my email record with vendors. I'm not sure who owns the service now, but I appreciated that. The second feature I like is their aliases. I use them a lot for security. You choose a prefix that you can add up to 125 suffixes (vs 10 max that I've seen elsewhere) connected with a "-". If your prefix is "myprefix" and you want to create one for a store, you would create an alias "myprefix-storename@*****". If you don't want to get more mail from 'storename', you should be able to use their 'unsubscribe' function -- but in some cases the store kept sending me mail, so I just deleted the alias. A while ago I saw that gmail had aliases: your gmail name "+storename@gmail.com". I don't know if there's a limit, but anyone or any machine can get your real gmail address from this. Netaddress' user-defined prefix approach prevents anyone from knowing your real usa.net address. The alias feature is important to me. I had to get a gmail account for my android phone, but I hardly use it. And Google's business policies are far too intrusive for me. So I'm glad to pay only $40/year for it. I can handle 11 cents a day.
