The mailing list for listmasters using Sympa

[address@concealed]

hallo list,

i'm running sympa with postfix as MTA. when posting a message i get
"send_mail : action succeeded" wwsympa.

BUT: no mail is recieved.

also the log seems fine:
Jul 10 17:29:41 bridge4 sympa[12824]: Processing web message for 
address@concealed from address@concealed
Jul 10 17:29:41 bridge4 sympa[12824]: smtp::smtpto(address@concealed, 
address@concealed, )
Jul 10 17:29:41 bridge4 sympa[12824]: Open = 0

sent
Jul 10 17:29:41 bridge4 sympa[12824]: Reaper unwaited pids : \nOpen = 0

in aliases i have entered the following:
oli_test: "| /opt/sympa/bin/queue oli_test"
oli_test-request: "| /opt/sympa/bin/queue oli_test-request"
oli_test-editor: "| /opt/sympa/bin/queue oli_test-editor"
oli_test-owner: "| /opt/sympa/bin/bouncequeue oli_test"
oli_test-subscribe: "| /opt/sympa/bin/queue oli_test-subscribe"
oli_test-unsubscribe: "| /opt/sympa/bin/queue oli_test-unsubscribe"

in db (mysql):

select user_subscriber from subscriber_table where list_subscriber='oli_test';
address@concealed

maybe knows how to solve this problem

regards 

oliver
