Then you verified the ID of the person who entered the address. If the delivery fails (read your bounces), you know who to blame. You could send new customers a conform message by mail too and if they don't confirm the link there, you know you can't reach them. > 5) the only very rare cases when the e-mail was wrong was due typo of > the employee Then use a machine and not paper and let the customer conform that spelling is right. > The recipient verification is clearly not an accepted way so we are > not going to do it. Then you will never have clue that the address belongs to the customer.

Indeed, but that is another reason why the address check doesn't work by testing the MTA. > Recipients are not possible to check because other people/company > used it in a wrong way and the VRFY commands is often disabled. > RCPT TO is not accepted and blocked by many operator. > Ok, message received! Spammers use list washing services to remove undeliverable addresses and spamtraps from their address lists. This is technically not different from your proposal. > But remember we are not trying to spam, spoof or fraud anyone. Spammers are saying that too and there is no way to distinguish. That's why certain MTAs are configured to make address testing uncomfortable. -- Gruß Marco Send unsolicited bulk mail to [email protected] _______________________________________________ mailop mailing list [email protected] https://list.mailop.org/listinfo/mailop
