Want to help?

We're looking for volunteers to help with some of the systems.  Here are some specific examples:

  • Reply to some of the random emails that get sent to the wrong place.  (for example, "How do I do X in Perl?" sent to the webmaster address.)
  • Improve our spam filtering.  (Also, clean up our postfix setup.)
  • Migrate services to Docker.
  • Identify inactive Perl Mongers groups (and clean up linked services.)
If you're interested in these (or other projects), please drop an email to webmaster at

Update: We received a lot of responses and are working with our first batch of new volunteers to get these and some other projects done.  Thanks to everyone who responded!

DMARC and Mailing Lists

We have reverted the filter that rejected postings to mailing lists from domains with strict DMARC configurations.  (For example: and

Unscheduled Unavailbility

We're currently having (unscheduled, unplanned, unwanted) unavailability of services.  We think it's a hardware failure in the critical path.

Apologies for the disruption.  We'll update this post as more information becomes available.

Update: 8:00pm America/Los_Angeles.
Everything is back up now.

We have experimentally enabled greylisting on the mail servers that accept mail for and and some other domains.

We expect that this will result in a reduction in the amount of spam that makes it through our filters.

You may notice a slight delay in mail delivery, as your MTA may have to retry to satisfy the greylisting filter.

7/18/2014: Scheduled Maintenance -- Moving Day!

More details afterwards, but most services will be unavailable for most of the day on Friday, July 18th 2014.  We're moving!  DNS will still work, but anything running on one of our machines (many webservers and mailservers, etc) will be unavailable.  We'll post updates here.

export TZ=America/Los_Angeles


  • 8:48AM - the first batch of machines shut down and powered off cleanly, which is a good omen. We're in transit to the datacenters at high rates of speed and the unracking will begin when we get there. 
  • 10:02AM 7/19/2014 - apologies for not posting any updates during the day yesterday, we were busy with actually doing the move.  Current state is that we're having trouble getting one of the key vm-hosting machines to boot, and the VMs on it include key servers.  We'll keep working on this this afternoon.
  • 2:00PM 7/19/2014 - the last machine is up and happy again.  everything should be working fine now.
