So if this is the case, then the energy company should do the job of verifying customers' email addresses themselves, not ask you to do it. > I haven't any knowledge of that flow but I think the digital signing > procedure link is one of the first step and need to be sent by > e-mail. > So if the user is not the correct one or the address is not right it > comes to they attention very soon. So that's actually a way of verifying the address and they are doing it themselves. So it seems unnecessary/superfluous to ask you to do it. > But remember we are not trying to spam, spoof or fraud anyone. *I do* understand it (I cannot speak for the others on the list), but because nowadays spammers do RCPT checks on a massive scale, then many recipients treat *everyone* who does it like a spammer - simply because there's no way to differentiate a RCPT check done with good vs bad intention. BTW, it's interesting how times have changed. Like 10-15 years ago, RCPT check was used as an *anti-spam* technique - quite a few anti-spam packages implemented so called "sender address verification" on *any* incoming mail, as it was quite common at that time to send spam with non-existent sender addresses. There's even still a configuration option in Postfix to turn this feature on... Now, if you do what was once an anti-spam measure, you are treated like a spammer... My personal opinion is that checking if an email address exists should be a normal and allowed thing. VRFY should work, and RCPT checks should not be penalized by the recipients. Security by obscurity (ie. by hiding the fact of existence or non-existence of an email address) was never a very good concept after all. There should be probably some per-client limit on address checks that are not associated with another email-related actions, like sending or receiving a message, just to avoid overusing the recipient's resources. That's all. But this does not matter as the majority seems to think otherwise... :( -- Regards, Jaroslaw Rafa r...@rafa.eu.org -- "In a million years, when kids go to school, they're gonna know: once there was a Hushpuppy, and she lived with her daddy in the Bathtub." _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
