Hi Tom, hope you had a good thanksgiving!
Sorry for the (very) late reply here, but I wanted to follow up with some more info.
We recently started seeing Google (I also imagine other SMTP servers are as well) tighten their security around SMTP headers and were getting a lot of rejected messages as well. Essentially, the email printer was writing multiple TO and CC lines in the header, and the new RFC specification they are adopting says they should all be on one line.
I released a new version of the email printer that should fix this issue (puts the TO and CC emails all in one line in the header), you can read my notes about it here: https://www.signature.net/signature/doc/rel2201.htm
I believe if you use the new email printer, you shouldn't have to update any of your programs to modify the TO/CC addresses.
