I think some of what's lost in this discussion - and it's true this may be dragging the discussion off-topic, but seems as good a time as any to bring this up. Often times the individual maintaining the mailing list or sending out the emails, is not the same individual that administers and maintai

Re: [mailop] [E] What am I supposed to do with abuse complaints on legit mail?

Yahoo's Feedback Loop is DomainKey based, but their blocking is IP based. At least that's how it used to be. Never made much sense to me to have an FBL based on DomainKeys, meaning every domain name that sends from an IP address has to have a registered feedback loop based on the DomainKey. All o

Re: [mailop] No answer from abuse-att.net?

This is why I cringe everytime I see a provider asking you to "send an email to x...@yyy.com to get delisted." x...@yyy.com is going to get flooded with spam also. Whoever is on the receiving end of that email address isn't going to know what's legitimate and what's not legitimate. It's so much

Re: [mailop] Is there any analysis on root causes of mail account break-ins?

Don't forget local compromises - keyloggers, spyware, and other malware - running on an end-user's system. If you are checking your email with an email client and not entering your password every time you check for mail (which most of us don't do) then the password to your email is stored some whe

Re: [mailop] ATT.NET abuse_...@abuse-att.net contact ?

Just keep sending them an email everyday. Sometimes you have to send an email a day for a week or two before they pick up on it. Not sure why they haven't created a website form to submit these. Relying on email for delisting like this is a recipe for disaster. What do we set the Subject as to

Not to hijack this thread and send it off-topic, but I'm also seeing a lot of brute force attempts (mostly WordPress login attempts) from various and wide-ranging subnets of Microsoft IPs. Has Microsoft's network been compromised? On Fri, Jun 4, 2021 at 10:46 AM Jörg Backschues via mailop < mailo
