I have recently configured the mail server on Yunohost, and i would like to know how much this is safe.
For exemple, i would like to use it for some sensible usecases like the mail for my bank account, crypto, and all my other accounts, so if something happen on this mail, i will loose a lot of tings…
So my question is, what’s the safest beetween Proton Mail and the mail on Yunohost ? And should i trust it enough to make it my primary e-mail for all that services that i listed above ?
And also, is it important to have reverse DNS on IPv6 for emails ? It don’t seem to work for me
Hey!
If your server is down by hardware failure, or software bug, you will not be able to read your mails.
That’s why having good backup, easy recovery, hardware spare, etc. is needed. Always thinking about the worst situation can be a good training when you build a server (Ok, all my datas will be dead if a nuclear war will come… )
Yunohost people are working to have the best software config on top of your need.
On yunohost, you are the only responsible for the safety, backup, maintenance, update, other apps, etc… So if you are confident enough, you can go with yunohost. If not, let others manage your mail box.
Just disable ipv6 support for emails. It’s a pain to configure and will get issues even when fixed. It’s my point of view, maybe others have better experience with it
It’s nor really a problem use only IPv6 for SMTP. I manage some servers with no address IPv6…
It can be difficult to manage correctly the mails, depends on your use case, have good practices sending mails to not fall in the spams…
I prefer keep my personal mail as clean as possible, when you use a mail address for some services, sometime the address is resell to other publicity providers…
But is better have also a rescue email address.
You can verify also if your email addresses have been pwned here
Basic things : good hard to guess password, check for system updates regularly, if you don’t use an app delete it, subscribe to security github notifications for installed apps, make backups (incidents happen), etc…
Proton Mail manage your mails so you don’t have to worry about them.
With Yunohost, you are the only one responsible.
You can have some problems with blacklists or you can be considered as spam with Gafam. You can have hardware problems if your yunohost is at home or problems with your FAI and electric power failure.
That said, i host all my mails with Yunohost since 5 or 6 years ago. I disable Ipv6 (there’s an option to do it in Yunohost) , i use some borg scripts to save my mails , i have also a copy of them with thunderbird. And a backup of the VM.
I had some misadventure with disk failure, electric power failure ( 5 days when i was far away from my home ), blacklists, spam at the very beginning with microsoft but nothing that discouraged me. And i don’t loose anything. But what if the problems had lasted longer? I guess i use a VPS to migrate it in emergency and i don’t know if won’t have any new worries.
I think it’s more safest with Proton Mail but Yunohost let you better control, it"s more flexible to use alias, alias group (i don’t see a similar function with commercial mails) and i feel more free.
If you search security, use Proton Mail , if you search freedom, use Yunohost.
None. I’m running my own mailserver without using IPv6 for multiple users and since many years. But I’m using a fixed, good rated, very reliable IPv4 address.
Backups, recovery plans and tests. Firewall, relay emails.
I’d put it this way: if you really depend on those emails and can’t compensate for loss or outages, don’t just start. Get used to it: run your email setup, learn about the options of relaying and having multiple servers/IPs on your mx record. Learn about postfix to get some knowledge about your way around in case you need to debug email issues.
While hosting your secondary email address(es) you’ll have a lot of fun, be relaxed, get your main address forwarded, learn stuff.
Once you’re into the topic and feeling confident you can switch roles - let your own hosting be your main email and use your former, external email as your backup.
Taking a relaxed approach you’ll have a lot of fun learning!
