[Web-cyradm] Problem with upper Letters in Mail Adress

[Angelo Neumann]

Hi list,

we found one strange Problem, i never heard or saw that before.

On one Server, running SuSE 10.0,  cyrus 2.2.12 and web-cyradm lastest svn,
 mySQL and Postfix,  we miss Mails that where send to users,  but the Sender
typed the Adress in upper Letters.

Means;   a.bc at de.de  (normal Adress) but Sender wrotes to A.bc at de.de

At mail Log you can see "....smtpd/pipe relay=cyrus status=send...."
But, the Mail is not in the Mailbox;   you cant see it in (eg. Thunderbird),
and its not on the File System!   ???

Who eat it?  :)

Thanks and Greets
Angelo
