<div dir="ltr">Because I'm finally making an attempt to catch up on email I thought I'd share my perspective as a moderator/admin of the mailing lists for LCA2016 (and lca-announce) as well as a user of mailhost for normal email.<br><br>Following this thread the admin team disabled greylisting and SPF on mailhost which affects mail flow into LA's mailing lists (including LCA) and the various inboxes used by Council, the Admin Team, and the LCA team (among others). Whilst mail was delivered slightly quicker, the quantity of spam also increased notably.<br><br>Across 8 mailing lists, 11 RT queues (most of which had email addresses published somewhere), and 6 inboxes you can imagine that would be quite a time sink.<br>This meant:<br> - more messages clogging our moderation queues for Mailman (including the endless notifications and then the bounces as well), this might have meant that some false-positive moderated messages didn't get released as quickly as they should have or may have even been accidentally dropped.<br> - many spam RT tickets (and again more bounce messages) creating more work for the team to clear the queues so actual tickets could get our focus.<br> - so many SEO emails. I'm not sure who they think is competing for '<a href="http://linux.conf.au">linux.conf.au</a>' search traffic but it was endless. If I had a dollar for every SEO email maybe we might have been able to afford some paid SEO.<br><br>Based on these experiences (which I'd expect the other mailman moderators/admins, mailhost users would echo) I'd recommend the Admin Team enable greylisting and SPF once again. If configured well (as I believe it was previously) most users should barely notice a delay as repeat senders do not get greylisted again within certain time frames.<br><br>Thanks,<br>David<br></div><div class="gmail_extra"><br><div class="gmail_quote">On 17 January 2016 at 17:23, Russell Coker <span dir="ltr"><<a href="mailto:russell@coker.com.au" target="_blank">russell@coker.com.au</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><span class="">On Sun, 17 Jan 2016 03:44:32 AM Brent Wallis wrote:<br>

</span>I did not make any mistakes in the configuration of my mail server/DNS as such.<br>
The mistake was in deciding to configure it that way at that time.<br>

I think this lets Brent off on a technicality. ;)<br>
