OpenDNS Issue (Gmail.com)

So if anyone has been having issues emailing to gmail users lately I finally found out why.
OpenDNS apparently is having kittens doing proper resolves for any of it.

Now if you’re an OpenDNS user you might say my settings were wrong or something.
Well I reviewed all my settings (disabled all security stuff and filtering) and I would get a bunch of NXDOMAIN(3) errors.

host gmail.com:
gmail.com has address 74.125.228.53
gmail.com has address 74.125.228.54
Host gmail.com not found: 3(NXDOMAIN)

Whereas using he.net’s dns:
host gmail.com:
gmail.com has address 74.125.225.117
gmail.com has address 74.125.225.118
gmail.com has IPv6 address 2607:f8b0:4009:802::1016
gmail.com mail is handled by 10 alt1.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 20 alt2.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 30 alt3.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 40 alt4.gmail-smtp-in.l.google.com.
gmail.com mail is handled by 5 gmail-smtp-in.l.google.com.

Quite a big difference eh?

So for the time being we will stop using OpenDNS as our primary dns provider until the issue is resolved.

Updates 11-14-2011

So I installed z-push-2 from svn tonight.
You should probably re-add your account on your mobile device to pick up the new features.
(ActiveSync 14.0 supported now.)

New roundcubemail svn pull as well tonight.

I also bumped up the max supported connections per ip for imap connections.
Hope you folks are enjoying stuff still.

This is all…

SSL Certificate Update

So I finally found a solution for pretty much all of our encryption needs
for Inexistence services and such.

StartSSL provides a free SSL certificate service I have enabled all the
hosts that require SSL with new certificates so guess what this means?

No more stupid SSL connection errors no self signed nightmare.

Enjoy your encryption.
PS. If you would like SSL enabled for some reason on your site please
let me know and I’ll see what I can do (and if it’s even justified).

A little mistake big issue resolved…

Apparently while securing Inexistence (did an audit over the weekend) accounts,
I made an mistake of not adding false to the valid shells so pretty much all email was broken.

This issue has been addressed and all email accounts should work as expected.

If you were expecting an email and didn’t receive it I would email them and request them to resend it.
Thanks to George for the heads up about email being broken.

Sorry about this folks but hey you live and learn.

Once again we return to our normal scheduled program and enjoy!

Super Upgrade Mode…

So tonight I finally got to roll the Debian 6.0 (Squeeze) update on Inexistence.
There may be some hiccups for the next few days as I fix anything that it broke.

I also started rolling IPv6 support now.
I will start adding AAAA dns records as I continue to test the functionality of each host.
All AAAA records have been set for all hosts now.

So please be patient if you notice anything break, I will more than likely be made aware
of it as it happens and will fix it as soon as I can…

Thanks and enjoy as always!

Updates to follow below (for any hiccups and their fixes):
2011-02-17
Slight hiccup detected with sendmail: local emailing (aka cron jobs) weren’t working as
expected thanks to submit.mc snafu. Fixed now from my preliminary tests aka all
my cron job emails are coming in.

2011-02-19
Did some changes to apache2 to improve performance and security.
