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…

Webmin

I changed webmin around a bit folks.
It can now be accessed from the following address here.

Of course you must have login access to use it of course…

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).

IPv6 Mark2…

So I finally got IPv6 tunnels to work flawlessly on my home network.
I’ll be sharing the love with Inexistence as soon as I get over to it’s location.

So for anyone who was wondering yes we will have IPv6 services again.
More to come…

Zimbra… Maybe?

So I’ve been playing around in the background with mail servers.
You may have noticed connectivity issues (especially today 12-23-2010)
as I’ve been playing with alternative imap servers.

We’re now using the imap server dovecot instead of wu-imapd.

I’m thinking about installing the Zimbra Open Source Edition.
It would enable a boat load of new features that I’ve been drooling over
specifically CardDAV, iCal and CalDAV for contacts and calendars.

Anybody have an opinion on this suite?
Or any alternatives that they may have used that they recommend?
I’m open to suggestions before I dick with Zimbra…

Thanks in advance.

QoS Enabled (Again)

So I once again enabled QoS (I forgot to enable it when we came back to
using dd-wrt from the airport extreme).

For those who wonder what QoS is that explains it pretty well.

To explain it in easier terms I had to reserve part of the network so upstream
cannot be flooded causing a denial of service. Now mind you a very slight denial
of service more of a lag of service and this fixes the issue quite well. Sadly
this also causes another issue and that is people will now download slightly slower
from the server but everything will be more responsive so the trade off is entirely worth it.

The reason I re-enabled this service is because I’ve noticed several users sending very
large attachments (email) to yahoo. Now normally this isn’t much of an issue but yahoo uses
a deferral system the basically causes inexistence to keep retrying to send said email.
Which yahoo rejects until they decide when it’s ok for the email to be delivered.

(Yes we use DKIM and SPF so there is nothing I can do to accelerate it any further).

So for anyone sending email to yahoo and wondering why it takes so long for
them to get it, this is why and if you really care about the person you are sending
email to then I would strongly suggest to them to use a better service.

Gmail, Hotmail, MobileMe, and many more exist and do the job in a more
standards conforming manner that doesn’t piss off our server..

That’s all for now.

So once again we’re up to date…

Updates 01-05-2010

Once again wordpress has been upgraded on all accounts I manage to 2.9.1.

svn pulls have been performed as well.
apt-get stuff etc…

DKIM is rocking still…

And so ends another update notice.

SPF, DKIM, Mail Changes

I’ve implemented spf tags onto inexistence mail to help with spam filtering
(I’m currently just marking headers not failing stuff).

I’ve also implemented DKIM signatures for select domain names.
(Also not failing unsigned domains and all domains are in test mode).

But if you were expecting an email and haven’t received it and
they have confirmed they sent it please let me know…
I know internally there are no email problems so I will receive your notifications.

Thanks!

PS. If you all of a sudden cannot use your email client of choice
set the auth to LOGIN sometimes called PASSWORD
do not use the MD5 / NTLM stuff as you’ll need my help.
