webmail upgrade/move (OIT SysCore)

Our webmail service has been moved from it's old home (a Dell 2650) to a Sun V20z running Solaris x86 for various reasons -- primarily becuase the PHP accellerator that we were using under Linux just "stopped" working for some odd reason.

We've sorry for any of the webmail wonkiness you may have seen this morning/afternoon as a result. It seems to be rather well settled in now -- the ldap address book should be functional again, as well as the multi-byte character stuff.

A little more detail -- when we first had a problem with the PHP accellerator last thursday, we converted to using our central web server build for the webmail instance (something that was long overdue.) However, the central web server build's PHP LDAP was broken, in addition to it lacking multibyte character support. This may have caused problems with users who deal with non-western character sets, as well as the "Addresses" button not working on the compose screen. Also, the default file upload size in the central web server build was set to 2M -- this is what squirrelmail sets it's max attachment size to -- so that's why there seemed to be a smaller attachment restriction.

Currently, the upload size for the webmail instance is set to 8M, so more than the previous max attachment size in squirrelmail.

Note, if you must send big attachments, use a "regular" mail client such as Thunderbird, Mac Mail, or (:bleach:) Outlook, as the rest of our mail system does not have an attachment size limit.
