[amsat-bb] Problem Receiving AMSAT-BB

For the past week or so, I don't seem to be receiving the Daily Digest of AMSAT-BB, as I was before. I've tried all the usual fixes, without success:

1.) Checked spam filter settings, "junk" folder, and made sure that AMSAT-BB was on my white list. 2.) Checked the trash folder and message filters on Thunderbird. 3.) Tried unsubscribing to the list and re-subscribing. 4.) Finally, changed from Daily Digest to individual messages. No joy.

Any ideas? (Please reply direct)
