Fix "Value too long" when adding addresses to Postini's senders lists
The maximum number of characters for each approved/blocked list in the Google/Postini SPAM filter is 4000. which is typically about 100 to 130 addresses.
This is a limit set by Google/Postini and there is no way we can expand it.
If you are getting this "Value too long" error, try editing your current list to remove old addresses.
You can also consolidate multiple email addresses with the same domain an choose to enter only the domain name.
We do not recommend doing that with popular ISPs like Gmail, Yahoo, AOL addresses, as these are regularly used to send SPAM.
