Hi Alvin, gtalug mailing list periodically gets blacklisted by smamhaus on our IPv6 address, then I have to go to their website and de-list us, which takes a minute or two, but lately this started happening every other week or so, and it's been pretty annoying.

Hi Alvin,

long time :)

Have you been black listed by an RBL for a mailing list sending verification emails?

Another thing is to make sure you have a valid email address by sending an activation message. Lots of people will provide bogus addresses either deliberately or accidentally. You also need to monitor your outgoing email or track the bounce backs for email addresses that go away.

One of the problems you will face is that conventional wisdom is that responding to an un-subscribe button is just a way that the spammers validate your email address. Also People will just tag the messages as spam causing you to get black-listed.

Every few years I get blacklisted because I have someone running a small mail-list related to a Knitting e-commerce web site. The site admin is a good friend and I know they are very careful about the mail addresses in the list but bad emails still leak in.

Hi Evan,

The quick answer is that there is no agreement on best practise for unsub messages, the amount of verification (and time span of) and a number of other abuse related issues.

Here is what I personally (wrongly or correctly) do: Subscription (Opt in message / Confirm email message - 1 per day max three days) Unsubscribe - no message - just unsubscribe

never send any email from noreply@ I am not Google or Microsoft (and even the dentist around the corner is now doing that *sigh*)

When subscriber does anything on a link (Web) - send a confirm your request email

Hi all.

This question is asked of anyone who administers a mailing list about policies. I'm setting up a campaign-based mailing system using phplist (as opposed to a forum-type MLM such as Mailman) and I'm interested to know what policies or best practices you might have in place to address this specific question:

When a list subscriber goes to a link to change their preferences or unsubscribe, from what email address does the confirmation (for changes) or "sorry to see you go" message (for unsubscriptions) originate.

Does such administrative email come from: a) an identifiable member or the organization's staff? b) a postmaster-type alias? c) a do-not-reply address?

​Any feedback is appreciated.​
