Zimbra - How to Stop Automatically Discarding Spam

By default Zimbra automatically discards inbound mail that receives a high spam score (aka "super spam").  Although the score is configurable up to 100, this default could cause false positive email to disappear and make troubleshooting spam scoring difficult.

Change the default behavior using these commands:
su - zimbra
zmprov mcf zimbraAmavisFinalSpamDestiny D_PASS
zmprov ms <mta server> zimbraAmavisFinalSpamDestiny D_PASS
zmcontrol restart

Choose from these values:
D_PASS -> Deliver all spam regardless of score
D_BOUNCE -> Generate a bounce message
D_REJECT -> Reject the message
D_DISCARD -> Silently discard the message (default)

Outlook - Recover Edited Attachments

Some of my end-users do this from time to time: They open an Outlook attachment (such as a Word doc), edit it, save it, then close it.  Where is it!?  It's buried in Outlook's temp file folder, dude!

* Turn OFF "Hide protected operating system files" in Windows Explorer.
* Navigate to this path: C:\Users\USERNAME\AppData\Local\Microsoft\Windows\Temporary Internet Files
* You'll find a folder in there called "Content.Outlook" that should contain the missing files.  If the "Temporary Internet Files" folder appears as a big mess, then try accessing the path via UNC, instead of locally.

My 30-Day Trial of Google Apps for Work

Although I adore running my own mail server, I was curious about Google Apps for Work, specifically Gmail for Work.  Could it block spam as effectively as my own insanely-aggressive rig?  Also, if I ever got tired of managing my own server or (gasp) something hugely disastrous happened to my infrastructure, I figured Google Apps could serve as an apposite alternative or fall-back solution.  If nothing else, perhaps I could add this experience to my IT resume.  They offer a free 30-day trial, so I didn't have anything to lose.

I don't think it's necessary to go into excessive detail because I'm sure Google Apps for Work is already well-covered on the web, but long story short--it's an incredible bargain.  Google offers a tremendous number of features for the price--to the point it can be overwhelming.  In the end, however, I did miss the customizability of running my own mail server, so I asked Google support a couple questions.  My questions are below along with their answers.

Joomla - How to Modify RSSocial to Display Other Icons

RSSocial is an awesome free Joomla extension I use to display social media icons on my site.  Since it uses the Fontello Zocial font kit, I figured out how to modify it to display other social media icons.

* Navigate to /media/mod_rssocial/css and look at the rssocial-font.css file.  You'll see a list of all the icons types that RSSocial can be modified to actually support near the bottom.  Make a (mental) note of the type you want to use (e.g. rssocial-icon-appstore).
* Navigate to /modules/mod_rssocial/tmpl.
* Edit one of the unused social network php files (e.g. flickr.php).
* Modify the span to match the icon you'd like to display instead.  In the example below, I modify the Flickr settings to show the Apple logo instead.  I don't use Flickr, but I do use the Apple iTunes store for my podcast.

<span class="rssocial-icon rssocial-icon-appstore"></span>

MS Outlook - None of your email accounts could send to this recipient

You send email to a recipient, but immediately receive an error bounce-back message that says "None of your email accounts could send to this recipient."  I'm running Microsoft Outlook 2010 in cached mode, so I'm not sure if this issue occurs in other versions / non-cached mode.

The email address was originally entered by copying/pasting or clicking a hyperlink.  Unfortunately, this corrupted the recipient address by changing its type to MAILTO instead of SMTP.  This info is cached in Outlook, so even re-entering the recipient address manually does not fix the problem.

Resend the email, being sure to change the recipient type to SMTP before clicking "send."

* Open the original message in your "Sent Items" folder.
* Click Actions, Resend this message...
* Double-click the problem recipient address, the recipient info card pop-up will open.
* Click the more options icon (4th icon from the left), then "Outlook Properties."
* You'll see that the e-mail type is set to MAILTO.  Click the "Internet Type" button to change it to SMTP.  Click OK.
* Click Send.  PROFIT!
