This is mail sending 101. Pretty stupid but not untrustworthy. That will cause their email to get rejected for sure so they would have to fix that pretty quickly or risk going out of business since sending email is their primary function. Hopefully you just got a level 1 support on the phone and their level 3 mail engineers would know better and get that fixed fast. > A trustworthy operation, always takes care of the plumbing. Trustworthy from a spam perspective: 1. Reliable unsubscribe/opt-out process 2. Polices their outbound mail and takes action on abuse reports and compromised accounts or bad customers/senders. 3. Keeps their mail servers off RBLs and a high senderscore.org score. 4. Doesn't send spam/malware/viruses/phishing. UCE is different from spam and users should be able to unsubscribe from UCE. If the unsubscribe process just harvests/confirms the email address, then it is spam.
