So far I wrote my sieve script by hand, but now I am trying to put my
sieve-rules into group parameters. For groups where I have a single
sender put in it works nicely:
,----
| (sieve address "sender" "someone.somewhere.org")
`----

However, I could not figure out how to generate rules like the
following: 
,----
| if address :contains "from" ["name-LMehjL4SQ+Y@public.gmane.org", "else-UDnQCpdwoQ8@public.gmane.org"] {
|     fileinto "groupname";
| }
`----
I've tried to put a list, a long string, multiple sieve parameters and
other such constructs into gnus-parameters.

How does one achieve such behavior?

Thanks for your help in advance.

Greetings,
Jochen
