forwarding oddity

[Mario Ramos (Grupo GOWEX)]

Hello!

I'm not sure if what I'm going to describe is a bug/feature... or
perhaps I'm doing it wrongly, so apologies if it's the later.

I use precompiled kolab 2.2.0 packages running on Ubuntu 8.04.2  x86

Kolab manages several domains.

I need some users to be able to receive all mails from 1 account, but
also these users need to be able to send with a from of this account.

Let's say the account a at domain1.com should be received by b at domain1.com
and c at domain1.com
b at domain1.com and c at domain1.com should be able to send emails as
a at domain1.com


The way I do things is:

Create a user account called a at domain1.com (using uid: a1)

I put b at domain1.com and c at domain1.com as delegates of this account so
they are able to send with an a at domain1.com FROM on their emails.

As I also need all mail coming to a at domain1.com forwarded to
b at domain1.com and c at domain1.com, what I do is:
I go to the a at domain1.com administration interface and setup a
forwarding for this account to a-list at domain1.com

Then I log back as manager on the admin interface and create the list
a-list at domain1.com with b at domain1.com and c at domain1.com as members.
This way they receive mail for a at domain1.com

This works absolutely fine.


The problem arises with the second domain.


Create a user account called a at domain2.com (using uid: a2)

I put c at domain1.com and d at domain1.com as delegates of this account so
they are able to send with an a at domain2.com FROM on their emails.

As I also need all mail coming to a at domain2.com forwarded to
c at domain1.com and d at domain1.com, what I do is:

I go to the a at domain1.com administration interface and setup a
forwarding for this account to a-list-domain2 at domain1.com

When I click on the submit button I get a:


Errors:
Not currently in TRANSACTION state
Script was:

require "fileinto";
redirect "a-list-domain2 at domain1.com";


This error only occurs if the second account uses the same characters
before the @ symbol on the email address.

I.e. If I create an account called a at domain1.com with uid a1 it works fine.
If I create an account called a at domain2.com with uid a2 I get the
mentioned error.

Could you please tell me if this is a bug, or where I can start my
research of this error?
Google seem to say that this error is sieve related, but I'm not that sure.

Any help would be appreciated.

Thanks a lot.

Mario Ramos.
