hi
if you use wpe you can crash the map server.
which works as follows:


make sure that you have an email (with attachmend) (best would be only one email) in your email folder.

when wpe is ready and you are logged in:

- open your mailbox (only open it, do nothing yet)
- record packets with wpe
- open the mail
- if you have the mail on screen, got to wpe and press stop.
- a paket like this should be there: "41 02 xx xx xx xx" (keep that window, you'll need that later)
- now press right mouse button and than "send" (so that you can modify the paket"
- change all values after 41 02 to "00"
- send the paket, and close the send window (not the paket window which you recored before)
- go ingame. now should there be a blank email (not the one you opened before ) (no message) or similiar
- delete this email
- click on write, than than opne the inbox again, should be empty
- go to wpe
- send the non-modified paket
- the "lost" email should be open again
- press "return" -> map server crash.

i didn't set up a mysql server local, yet. otherwise i could give you the part where it crashes.

but i guess this is a nullpointer prob in clif_mail_ or somethink like that, didn't check further ...
