Jerry on Mastodon@hear-me.socialOPtoPrivacy@fedia.io•#YouTube is starting to implement age restrictions , globally, to control who watches videos with mature themes, violence, or explicit language.
1·6 months ago@[email protected] Frankly, I think Google has learned that people rattle their sabers and ultimately do nothing about it.
I don’t think it’s going to matter to them that a tiny fraction of people will stop using YouTube any more than it bothers Meta that some people use Pixelfed.
Jerry on Mastodon@hear-me.socialOPtoCybersecurity@fedia.io•I received an "important email" from #Dreamhost about my domain registration. You'd think that #email security would be paramount for them.
2·9 months agoOMG. It gets worse. The link in the email doesn’t go back to their own domain, or even one they control. It points to a 3rd party domain owned by Tucows called name-services.com.
They are training customers to let down their guard when using the link from an email they supposedly send. A scammer can get a similar domain name to easily fool people to click the link since customers have been taught there’s a 3rd party link.
They’ve done everything wrong relating to email security, and they are a web hosting company that should do everything right.
Jerry on Mastodon@hear-me.socialOPtoCybersecurity@fedia.io•Putting this out there for whatever good it does.
1·9 months ago@[email protected] This is a great idea!
Jerry on Mastodon@hear-me.socialOPtoCybersecurity@fedia.io•Did you know that if a spammer uses your email address as the FROM: address, which is easy to do, all the bounce messages will go to your email address? If the spammer really hates you, they will send
1·10 months ago@[email protected] This doesn’t involve security. This is just about a protocol that says a server must let you know, via one email for each rejection, that an email with your from address couldn’t be delivered, regardless of whether you sent it.
It’s a procedural problem.
If a spammer sends 5 million emails with your email address in the FROM: then you can expect hundreds of thousands of messages from your email provider telling you that it couldn’t deliver an email, for whatever reason.
Here. Let Google explain it: https://support.google.com/mail/thread/209018675/my-sent-email-box-is-filling-up-with-bounce-emails-and-emails-i-did-not-send-my-inbox-is-fine?hl=en

1·10 months ago@[email protected] No idea what you are saying here. But, you can argue with Google: https://support.google.com/mail/thread/209018675/my-sent-email-box-is-filling-up-with-bounce-emails-and-emails-i-did-not-send-my-inbox-is-fine?hl=en

3·10 months ago@[email protected] People are not reading. You are not reading.
SPF, DKIM and DMARC are not relevant. Those are instructions to the receiving servers which are not the ones sending the bounces. The receiving server is telling the sending server, based on these DNS records, that it will not accept the message. It refuses them. Period. No bounce message.
The sending server then, as a courtesy, lets the sender know, solely based on the FROM: address, that the email could not be delivered, as one by one messages.
There are no DNS records or configurations that control this. The SMTP server follows the protocol which is to inform the FROM: address, as a courtesy, that the email was not accepted. It is the sender. It does not look at SPF, DMARC, and DKIM rules. That is only what the destination server uses.

2·10 months ago@lautreg SPF and DKIM are only used by the destination IMAP or POP3 servers to see what to do when they receive the email. In this case they reject it.
The delivery failure message is coming from the sending server as a courtesy message to the sender to let them know their email was not delivered. The protocol is to tell the FROM: address that the email could not be delivered. The SMTP, sending server, doesn’t look at SPF, DKIM or DMARC or any DNS records or any other configuration related to it. It simply tells you the millions of emails sent with your FROM: address could not be delivered, one by one.
People keep bringing up SPF, DKIM, and DMARC, but it’s not relevant to this problem.

Firefox@fedia.io•So, I'm staying with #Firefox, even though their CEO is tone-deaf and clumsy and destroying #Mozilla's reputation because today I had to remove 6 extensions in #Vivaldi (my sometimes alternate

I didn’t remove them. They were removed and in the manage extension screen it listed 6 extensions that were removed

I like how you think!
Jerry on Mastodon@hear-me.socialtoNews from fediverse@fedia.io•Well, since Threads users can now see replies to their posts from Fediverse users AND they're public, I think it's as good a time as any to ask this again.
1·1 year ago@[email protected] I don’t block threads on my instance. I limit them because I think as they build out more integration, spammers will begin posting from there, given that it will take longer to remove them on Threads than on a Mastodon server. I have no plans to ever block Threads.
But, I have unlimited many Threads accounts individually, as exceptions, that I know are real and safe, and will do so on request.

I’m now expecting Elon Jr. (Spaz) to do the same on Reddit because Elon is his idol and mentor.I wish there was an option on #DuckDuckGo to exclude search results that point to Twitter since I can no longer read them. It’s now just clutter in the search results.

Exactly. As usual, the lawmakers worsen it. While trying to keep children safe, they are forcing them to use shady VPN services, which expose them to worse harm. Never changes.
But keeping children safe is not really their goal. It’s a lie that the gullible will accept and support.
