Sending Mail and kernel panic

Question

PLEASE PLEASE help me on this issue.
Since I updated to Leopard (which has been the biggest mistake so far) every time I try to send an e-mail (using Apple Mail 3.0) through my company's server I get a Kernel Panic issue in four languages and I have to restart my computer. The funny thing is that sending the e-mail through Gmail's server works fine.
I don't know what to do, but its driving me crazy.
I appreciate all the help I can get to solve this problem.

Thank you for your post!
Here are some troubleshooting steps for you to follow that may help you attempt to rectify your problem.
(1) Please ensure that you have ran all software updates: Apple, then Software Update, then install all updates that are shown. Once updates have been ran and you have rebooted, continue this process until it says no more updates are available at this time.
(2) What happens when you log into your companies webmail and attempt to send a message on the same connection? Does the same issue occur? If so consult with your IT administrator and see if other Macintosh users are having a similar problem.
(3) What happens when you attempt to send Mail in the activity pane? Click, (at top of screen) Window, then Activity pane before the panic occurs?
(4) Try creating a new user in System Preferences, then Accounts. Once you're in System Preferences, click on the Accounts icon. Then click on the padlock, and authenticate with your Administrative password. Click on the "+" sign, then the drop down that says "standard", and change that to Administrator. In each field type the word "test", and then click create account. Close out of System Preferences, then log out of your user account (Apple icon, then log-out). Once you've done this launch mail in the test user and reconfigure it with only your work mail account. Does the same issue persist in the new user when attempting to send mail? If so boot to your install disc for Leopard and run Disk Utilities Disk First Aid- Repair Disk and then proceed to Archive and Reinstalling your operating system preserving user and network settings.

(5) If you're able to send Mail successfully in the new user log out of test and log back into your user account as you've isolated the issue to be user specific. Go to System Preferences and delete the test user account then once you're sure no application is open such as Mail open a Finder window and then navigate to your Home folder, then Library, then Mail. Click and drag the Mail folder to the desktop. Then click Preferences, and find and remove com.apple.mail.plist to the desktop as well. Log out and log back in. Relaunch mail and reconfigure your mail account for work. If you click on Mail, then Preferences, then Accounts, make sure only your work account is listed in an attempt to remove any other variables. If the Google one is still listed remove it. Then re-add your work account after confirming the outgoing mail address with your IT administrator and the correct port number in addition to whether or not SSL is required and what type of authentication is necessary. If this works, then trash the .plist and leave the Mail folder on your desktop in the event you need to revert to your old database for whatever reason for at least a week or so till you're sure the problem has been permanently resolved.
Some other ideas that I have include:
* Are you hard wired via ethernet to your works network? Is there a wireless network that you can connect to via Airport disabling your ethernet connection? Attempt to send mail from that and see if the unit continues to kernel panic.
* Make sure any peripheral devices connected to your computer are removed (you never know, unlikely yes, but to be safe I'd remove them).
* If you upgraded from Tiger archiving and reinstalling preserving users and network settings may very well resolve your issue. Only do this after isolating that the problem is system wide across the OS.
* Leopard may not be compatible with your network at work for whatever reason, archiving and downgrading back down to Tiger 10.4 is always an option as well. Just make sure to use your Tiger disc and run software updates after to ensure you're on 10.4.11.
Making sure you have a complete backup prior to archiving or making any system modifications is equally as important especially if it's your work machine.
Hope this helps! :-D
