usernames containing @ (cyrus 2.1)

[gregor.bruhin at netoxygen.ch]

Hi,

I currently have to migrate an imail server to our cyrus server perhaps somebody had the same issues I have ...

All users are using this style of usernames: user at domain.ch

I tried to create a new mailbox with such a user it worked, authentification works also, mail routing also. But it seems that the mails can't be delivered because the mailbox can't be found on delivery.

Is there an easy way to solve this ?

Thanks for your help, Greg
