Remove Amavis Content Filter From Postfix Configuration, Requeue All Postfix Email Messages

I installed ISPConfig awhile back on a web hosting server that at one point also hosted email accounts. I recently moved all of the email to a different server and wanted to cut down on CPU and memory usage so I needed to disable amavisd, clamd, courier-imap, and courier-authlib. These services provided a way to receive email via POP3 and IMAP as well as content filtering and virus scanning for all of that email. So after shutting all of the services down I needed to remove the reference to the local content filter from Postfix because if amavis is shut down and mail is sent from a web application to the localhost then the connection will be refused and Postfix will not send the email. Below I describe the Postfix configuration lines to comment out as well as a way to reload all of the queued email into the Postfix queue so it could be sent again.

Configure Evernote For Offline Access on iPhone or iPod Touch Via IMAP

I recently started using Evernote to store all of the notes I take on a daily basis across plarforms. Evernote allows me to take notes and sync between numerous computers, my T-Mobile Blackberry Curve, and my iPod Touch. One thing that Evernote lacks is a solid method for accessing my notes when I am out of range of an Internet connection. I was pleased to learn that you can actually access your notes offline via IMAP and even though it is not ideal its good enough for now since every other part of Evernote is top notch.

Outlook IMAP Accounts: Download Headers Only or Download Complete Items Including Attachments

When settings up an IMAP account in Microsoft Outlook you will download only the headers by default. Personally I like to have all of my emails easily accessible online and offline even with IMAP accounts so below I describe how to setup your IMAP accounts to download the entire email message including any attachments.

Follow the below steps to setup a custom Outlook send and receive group. In this group you can pick and choose which accounts to includes and which IMAP folders to download. For each IMAP account you can specify numerous different options including if you want to sync a specific folder, if you want to download only the headers, or if you want to download the entire message including any attachments.

  1. Open Define Send/Receive Groups: First you need to open the “Define Send/Receive Groups” within Outlook. Click on Tools in the top navigation menu, then select “Send/Receive” from the drop down, followed by “Send/Receive Settings” from the pop out menu, and from the second pop out menu select “Define Send/Receive Groups”. The menus are shown below in the image.
