This worked for me on for the VTLEPS listserv:
Click the gear icon on the upper right. 
Click "settings."
Click the "Filters and Blocked Addresses" tab at the top. 
Click "Create a new filter" near the bottom. 
Put "[log in to unmask]" in the "from" box, then click "Create filter 
with this search."
Check the box "Never send it to Spam," then click the "Create Filter" button.

       Do other Gmail users have a problem with VTBird messages being tagged as
Spam? Lately, about half of them are going to the Spam folder. I have
VTBird in my Contacts, and I have a filter set up to send messages from
VTBird to a folder (i.e., "Label" in Gmail terms). Does anyone have a fix
for this?
