Hi Gusbythebeach 

Some Gmail is getting rejected by the TalkTalk Mail servers with a TT406 bounceback that indicates previous mail being sent by the same Gmail server IP address has been deemed as spam.  This is because Gmail are currently sending a lot of spam to TalkTalk customers.

It's up to Gmail to improve their reputation by stopping spam at source.

Your Gmail user has two options:

1. Report the issue to Google / Gmail
   The last time this happened Gmail switched the sender IP address to a new one
   Doesn't stop the spam but allows a breathing space with a 'clean' IP address in use
2. Use a non Gmail address to communicate with you until Gmail do stop sending spam
