Our main domain "mailvox.it" is listed on ivmURI since 4 days (we are an ESP, a very small "Mailchimp" of the italian market, we share the same Freemium plans and the same opt-in required in our ToS).
That domain is the reverse of all of our IPs and it also used in the return path and in the "tracking pixel" of all of our emails, or to say it better, all of the emails (1-5 millions per day) of our users/customers (10K). We don't use "multiple domains" (that domain is there since 2008 in all of our emails) and the IPs are shared. All of our emails have List-Id identifying the real account (user/customer) responsible for sending the email. I sent the delist request as explained in the invaluement website (#7850A471D5#) a couple of days ago but I had no answers. Last time I tried that was more than 1 year ago, with no answer, but the block disappeared weeks later. Does anyone know how ivmURI is "fed" with spam and how they deal with false positives? The ivmURI description say "These domains are generally not seen in legitimate e-emails" but while some spam may pass our customer vetting and internal antispam measure (we try hard to do our best in this), I really think most of the emails sent by our users are legitimate and opt-in. Rob (i'm not sure if I could CC you by the etiquette of this list), can you help identify the source for this block? Anyone else have similar experience with shared ESP domain blocked by ivmURI? I also see some servers quitting the smtp conversation from my IPs because of ivmURI matching the reverse of the domain or the EHLO, or the rfc821 from address: is this an "expected" usage of the ivmURI or is this a "misuse" of that list (meant to match uris in email content) by their customers? (of course Invaluement is not resposible for that, I'm just trying to understand). Thank you, Stefano -- Stefano Bagnara CTO VOXmail.it
