Dealing with many “Mail Delivery Failed” addresses

When spammers sign up for your website, you get a lot of junk email addresses.  If you then institute a newsletter module, you may get several hundred “mail delivery failed” messages.  

In Apple mail, you can select all the individual messages and click “forward” to compile them into a single email.  (If you use conversations, first do View->Expand All Conversations in order to select individual messages.)  Then copy that, paste into, and you’ll get a list of the email addresses that bounced, which you can then bulk unsubscribe.  This works for me with the Drupal Simplenews module.

How do we know what other people know? (rough cut)

…without talking to them, of course.  [Note: This has been sitting in my queue since September; I’m going to publish it as-is so it counts as “done.”]

  1. Papers (external)
  2. Reports (internal)
  3. Blogging

Blogging is like talking to them, but what’s the impetus to get a blogging (internal or external) program going?  The NSF problem: how do you know it will work (i.e., help everyone know what everyone else is good at) without doing it first?  Blogging as a fun part of work, not as a chore.


  • to help make skills more widely known in-house
  • internal development
  • internal culture
  • not aimed at promotion of organization

    • however, good bloggers are good ambassadors to the public and future partners
    • external blogging is useful to draw in experts from outside the organization
  • Good points:
  • More good points:

Time commitments and return.

Personality of bloggers and readers–some people like to write, some like to read, some are a mix.  Some would rather just talk to you.

Do some searching on this, maybe case studies are out there?

This is not what I am talking about (internal blogging for an external blog).
