You may edit your email account settings in Comdo AntiSpam.
You could find you account in 'Account' page of Comdo AntiSpam configuration, then select the account you want edit, here is you gmail account, you could edit it by 'Edit' button, which will bring one edit dialog of selected account. You could fill SMTP settings for your account.
Generally, Comodo AntiSpam could grabber your accounts settings, but it will fail for outlook2007 if it imports accounts from other e-mail clients.
Hope this helps.
