I used Spamato with my outlook 2007 first and recently switched to Spambayes because Spamato simply wouldn’t work with Windows 7 even after going through an enormous hassle of hacking Microsoft’s .NET Framework 1.1 installer to get it to install in Windows 7.

I’m really glad I switched, SpamBayes has amazing accuracy when trained with your Spam/Ham folders. It even has a ‘Junk Suspects’ folder which has caught all (1 or 2) my ham messages which is mistook for spam. I don’t think any Ham has ended up in the Junk folder unless it was an automated mail/newsletter and those quickly stopped going to junk after useing the ‘recovering from spam’ toolbar button to improve training.

I used Spamato for more than a year and it works fairly well, I liked it and recommended it to others. Every time I recommended it to a non technical person I cringed a little bit after remembering the fact that it requires a couple, not so simple to explain over the phone, prerequisites.

The finite accuracy seems better in SpamBayes and the installation is definitely a hell of a lot easier than Spamato.

My Answer: Goto Email Accounts, Change the problem account, More Settings, Outgoing Server tab, and check outgoing server require authentication and choose “Log on to incoming mail server before sending mail” instead of “Use same settings as incoming” – Outlook 2007 is the first and only mail program to require any of our mail servers to use this setting. So far I’ve only confirmed the problem to be on older sendmail servers. There can be other solutions to this error message but this is one I find most often resolves it.

The Question: As a systems administrator I take calls for our tech support queue and one user called with a really odd problem. Basically it’s detailed here:

http://thepursuitofalife.com/outlook-2007-error-none-of-the-authentication-methods-supported-by-this-client-are-supported-by-your-server/

Like the above link describes the user would have to disable SMTP auth in certain locations (That’s a workaround, not the solution), even though all our servers require SMTP authentication. The above link eventually shares the true solution but it’s buried under many comments thanking the poster for the work around. So I decided to help fellow googlers by making this post.

Update: Comments about other people’s experience with this error made me want to add my further experience with it. I’ve seen this error a lot more often since I first made this post and am convinced it’s really some sort of bug with Outlook 2007. Some people cannot get rid of the error and have to continually switch between “Log on to incoming mail server before sending mail” and “Use same settings as incoming” to keep outlook sending correctly. Whereas if they switch to Windows Mail (The Vista and Windows 7 equivalent of outlook express) they never need to do anything but set ‘use same settings as incoming’ and never have any problem sending. If it’s not a ’2007 Bug’ then it’s definitely a Outlook 2007 incompatibility with certain MTAs – specifically (maybe just older) sendmail – our postfix servers don’t seem to have this bug, but like I just said only 2007 has this incompatibility so you can’t entirely blame sendmail.

Windows 7 bugged me about anti virus right away so I grabbed that first…

AVG Free
Firefox 3
Nvidia video drivers, found out they’re integrated in windows update for W7 Beta.
UltraVNC (for work)
Steam (For Team Fortress 2 and Left 4 Dead)
Set my workgroup to reach my samba shares (control panel > system > change settings > workgroup)

W7 Then bugged me about a product key so I registered a windows live account and they emailed me one after a few steps through their site (Looks like they haven’t run out of their 2.5M keys yet)

While I was browsing some websites I noticed something foreign to me…ads, I realized I had forgotten the holy grail of Firefox addons, adblock+ and Filterset.g. Continuing my application installs…

Creative SBX-Fi Drivers
Foobar 2000 (music)
VLC (video)
CCCP (Video Codecs & MPC)
Logitech G15 Keyboard Drivers.
Ventrilo
WinRar (surprised I didn’t need it before now!)
Foxit Reader (Free Adobe Acrobat replacement & improvement)
CDisplay (aka Comic Book Reader)

I then “unpinned” Window Media Player and Internet Explorer from W7′s new taskbar and pinned Foobar and FF3 instead. The new taskbar is a nice merger of quick launch icons and task bars applications.
