Hey, does anybody have the same problem when sending email to sales@ ?
"Delivery to the following recipient failed permanently:
sales@spondoolies-tech.comTechnical details of permanent failure:
Message rejected by Google Groups. Please visit

Edit: cc of the same email sent to a person at spond seems to go through fine, so problem seems to be at sales@ address
I've gotten this problem a lot in the past too. I think if you send the same message from different email addresses, then Google will just think you've got several email addresses that are working in collusion to send spam. Try sending an email to a specific person at Spondoolies (e.g.
katyap@spondoolies-tech.com or barbara@) instead of one of their shared email addresses, as the individuals' addresses aren't mediated by Google Groups. You should also forward the error along to stas@, as AFAIK it's his job to make sure this works.
I got this to work by clearing out the included message history. Start with a blank slate and include just the last two message history.
