[Dovecot] Redirecting mail gives 'mail forwarding loop' to the sender - calling for sieve help

[Andrés Yacopino]

Yes, that is a global script.
Yes you are the right , the script is executed again but i thought that 
this line do the verification to avoid this:

if header :contains ["To","Cc"] "userA at acasalud.com.ar"

It seems it didnt' but why?, can you explain better?

Thanks a lot,

Andrés Fernando Yacopino
