Or at least that was the case when my friend with VZ DSL tried to send e-mail through VZ from her personal domain.IOW, VZ isn't even checking to see if a zombie'd host is forging its own domain into HELO, regardless of whether it comes from Comcast orUUNet, and as long as the forged sender has a verizon.net address, andthe recipient hasn't blocked VZ's silly callback system, the message is relayed. Thanks, Verizon. We can hear you now.Assuming it does via their systems - most zombies have their own smtp engine from what I understand
Zombies do both, but my comment wasn't about zombies, it was about users. If you are a user with a vanity domain trying to send e-mail "From: user@vanity.domain", you cannot through VZ's system. Despite the fact we have spent years telling people they have to use their local ISP's mail server to send mail out.
Does VZ support SMTP AUTH these days? (My info is over a year old.) -- TTFN, patrick
