but sometimes you just have to educate your users going forward.
I again suggest you do some better reading of what I write to you. I -do- educate my customers as I explained.
Why would an ISP block access to their own (the ISP's) SMTP server?
That is not what I said. I said -limit- it to their own SMTP server. Limit to means that their customers can use their own ISP's smtp server but no other (on port 25).
Is all email communication mandatory over TLS? Do you require SFTP? Is DirectAdmin behind a TLS connection? Then I totally agree with you, that's indeed not bad hosting in my book.
I'm glad we agree.
But as said, Letsencrypt is too young and even renewing still goes wrong too much. So yes this has to be done, but not right now, but when it's stable and that is indeed not bad hosting if you provide customers only things that are well working and stable.
DA behind a TLS connection? You mean behind a SSL connection.
We do provide TLS for mail and SFTP for FTP, but we do not force it to our users yet.
So tell me, why would you?
Do you block mail of other hosters without any good reason, without providing them am a good way to get delisted while they are complying to all RFC's and your rules and are not on any spamlist?
Microsoft is doing that, so why don't you?
If you make unstable things mandatory for your users, why would I?
The "They do it so you should" is a nonsense argument.
In my opinion I do it better then you if we're talking LetEncrypt imho. At this moment I provide it as a choice. Later on when it's stable, then it will become mandatory.
You don't always have to wait until a feature is implemented by your platform provider.
I know and it's nice if others implement things earlier, mostly with several problems which appear which DA support might not be able to fix for you. For bigger companies this is a lot easier then for smaller hosting company's.
Wildcard SSL certificates are often too expensive for smaller companies. So yes, now with LetsEncrypt which is a lot cheaper, -and- the support from DA which incsludes SNI and mail-SNI makes it way more possible to go forward.
So no you don't have to wait, but it won't help a lot either if most of the others still won't follow the flow of improvement, which is mostly done if also MTA's and platforms provide support for it.
Again, like Google, Microsoft and Apple "forcing" their users to use secure protocols?
Again "they do it so why shouldn't you" is a nonsense argument. Those are big company's with loads of money, so they can easily buy official certificates, and buy a lot of knowledge to implement it and solve eventual problems when occuring. That's why those company's can implement so early.
Wow, so just because not everyone's on board yet, the rest of us can't move forward.
LoL. Read my comments about agreeing to part of this. Implementing SPF and DKIM records automatically is moving forward. Changing ~all to -all is not.
You know as well as I do that SPF:
a.) Just isn't working that great because there are way lot of MTA's which do not even check for SPF records, including what I already stated a lot of big ISP's. I didn't here you about that. SPF works or dies with the amount of systems using it, you know that as well as I.
b.) When looking around, the times that spammers are faking hostnames which SPF would block, are not a lot anymore, they have lots of other ways to abuse the systems.
Which doesn't mean we can't improve things, but changing that is not that big at this moment.
I'm sorry, but I fail to see what router IP addresses have to do with the SPF issue we're discussing here.
I'm sorry, I was under the impression that you knew how SPF worked. Or you did not read my comment good enough. I suggest you do that. I did not spoke about router ip's.
And I didn't get an answer to my question if you are going to teach your customers how SPF works and how they change DNS records and when their ip change how they can look it up etc.
Unless you're going to use their ISP's domain for mail, which immediatly makes it possible for all other customers of that ISP to send mail in behalve. And then we did not talk about the business customers and some ISP's which do have real static ip's. So which need change. That was what I was talking about. Not routers.
