And the whole topic raised here doesn't even feel operational to me. Whether or not somebody SMTP verifies email addresses or not, why they can't just simply implement double opt-in, whether or not the next mail attempt to the recipient in questions bounces, nothing here feels operational in nature. These feel like strategic business or marketing related considerations. There's no way that any choice picked here significantly impacts the operational uptime of a mail server. Operational considerations seem like they'd include server configuration, email authentication settings like SPF, DKIM, DMARC, TLS, logging, queuing, bounce handling, good neighbor tables/rate limits, maybe blocklist monitoring, and devops stuff. The plumbing.....I'm personally not hearing any of that here. Wrong forum, wrong questions, wrong audience. Regards, Al Iverson PS - Just do double opt-in and get over it already. Email verification only inexactly proves that an address is VALID, but not only does it not do so 100% of the time (it is very tricky to do at scale and not always welcomed by receiving mailbox providers), it also does not stop ME from filling out the form with YOUR address, accidentally or intentionally. As John Levine and others have said, it doesn't verify that the person with that mailbox is the person who wants to or expects to receive that mail. If you need absolute certainty, email verification surely doesn't seem to cut it. It is more often utilized in marketing contexts with the understanding that it essentially helps some folks kick out certain types of bad addresses; not that it magically or always proves that every valid address is correct. -- Al Iverson // 312-725-0130 // Chicago http://www.spamresource.com // Deliverability http://www.aliverson.com // All about me https://xnnd.com/calendar // Book my calendar _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
