[exim] Blacklisted @ gmail.com

Hi

Can You tell me what can I do to be unblacklisted in gmail spam filter?
For one week ago I had open mail system and some spam passed from one of
my servers. Today I filled out the form at
http://mail.google.com/support/bin/request.py?contact_type=msgdelivery&&hl=en
<http://mail.google.com/support/bin/request.py?contact_type=msgdelivery&&hl=en>.
Can I do something more?

Regards!
