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.

HTML Validation (Google Analytics + Cloudflare Bug)

You may have noticed recently if you do a validation check on your sites code and it
comes back with four errors. This is Cloudflare’s injection of Google Analytics
on your site causing this issue.

I filled a bug report with them and once I get a reply
I will post here with either the final solution or a work around.

Apparently the issue has been fixed, cloudflare was “nice” enough
to not inform me and just deleted the bug report… *sighs*

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!

Roundcube

So I did an svn pull a couple of days ago that apparently exposed some bad values in the config file.
I had a merry task of hunting it down, first I thought it was the imap server causing hiccups.
So I tried all sorts of crap including downgrading to an older copy of roundcube.

Finally I decided to diff -urN the conf files and just update everything.
And now I’m pleased to say cubemail works again for everybody.
(at least it should)

Sorry about the interruption of service but at least it didn’t take too long to fix imho.
Enjoy!

SQL the constant headache…

So tonight I went from the stable version of mysql 5.0.51a to 5.1.49 from debian backports.
*Sigh*

We’ve been having issues with database corruptions hopefully this will help out.
Please let me know if any of your sql powered sites have issues…

As always enjoy and I hope everything is great on your end…

Update – 10/18/2010
So the backport upgrade really didn’t help much…
I now have a custom shell script I wrote checking the databases every day around 4am.
If you site goes down around then don’t be surprised and a refresh of your browser should do the trick..
(It takes about 2 to 4 seconds to run and re-spawns mysql to fix the OOM issue it still causes)
I cannot wait till squeeze comes out (next version of Debian).

That is all…
