[Mailman-Users] Problem

[Nookie]

Hi!

I have problem ... when I try to subscribe from my second address 
(koszym at poczta.onet.pl) subscription request (to my list) I got this error 
...

Jul 13 16:54:08 localhost postfix/smtp[16418]: 6ACC84F6FA: 
to=<koszym at poczta.onet.pl>, relay=poczta.onet.pl[213.180.130.206], delay=1, 
status=bounced (host poczta.onet.pl[213.180.130.206] said: 550 5.7.1 This 
target address is not our MX service client: <koszym at poczta.onet.pl>)

And i ahve question .. its postfix error, poczta.onet.pl server error or 
mailman error? and maybe someone can help me...
