    Email Privacy

    I originally posted this at http://www.318.com/TechJournal Ever get an email from yourself that you didn’t send? Ever get spam from someone that you can’t reply to? Using the settings of an email program, it is possible to pretend to be anyone that you would like. If you want to send email from bill.gates@microsoft.com then that is entirely possible. Finding the address of who actually sent email is easy, but ensuring the identity of the sender is not part of standard email. This is where the protocols for PGP, Pretty Good Privacy, and GPG, or GNU Privacy Guard, come into play. GPG and PGP are Open Source suites of applications allowing…

    Exchange: Increase Maximum Database Size

    Exchange has a maximum database size of 16GB.  You can temporarily increase this if you exceed it by editing the registry.  To do so, open a registry editor (Start -> Run regedit) and browse to this location: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesMSExchangeIS Now, find the name of the server whose database you would like to increase the size of and click on it.  Then, click on either the folder that starts with Public- or Private- according to which you want to increase the size of.  Now add a Reg_DWORD with a name of: Database Size Limit in GB Now set the setting for the limit to 17GB (just type in 17) and reboot the…

    Functionality Differences between Microsoft Entourage 2004 and Microsoft Outlook 2001 for Mac

    I originally posted this at http://www.318.com/TechJournal Entourage 2004 has more options than Outlook 2001 but also does not communicate over MAPI but instead over WebDAV (OWA). The Graphical User Interface (GUI) level changes are too numerous to review. A conversion from Outlook 2001 to Entourage 2004 requires retooling the workforce for the new application. Schedules, cached email addresses, signatures and other settings will be lost during the migration, but mail, contacts, calendars, to-do items and tasks should survive the migration. Once common theme across the two is wasted resources. Outlook 2001 required OS 9 to run in OS X. Entourage 2004 requires Rosetta to run in OS X. Both waste…

    Using a + in an email address

    If you take an email address like my iCloud account, it’s krypted@me.com. If I take the username and add a + at the end I can then type some characters and put it all in front of the @ and domain name then the mail will still come to me. So, let’s say I use it to create an AppleID for an APNS certificate. That would be: krypted+apns@mac.com Or iTunes: krypted+itunes@mac.com Or iPhone1 (or these days iPad1): krypted+ipad1@mac.com The only gotcha is that occasionally you’ll run into some field on a webpage that has input validation for non alpha-numeric characters. Shouldn’t be the case, but it comes up from time…
