email configuration for RTC

You can change the email settings by going into the JTS web admin interface:
https://<server name:port>/jts/admin#action=com.ibm.team.repository.admin.configureMailSettings
In here you can change the email "From" name, and "SMTP Reply" addresses.
Up to version 5, you cannot change this on a per project basis. Also, I'm not sure what emails you would send out on such an interval as 15/30 days, but you can change some interval settings in the CM admin interface, although these intervals are likely not what you are looking for:
https://<server name:port>/ccm/admin#action=com.ibm.team.repository.admin.configureAdvanced
