Any comments from TalkTalk about this?


Message 1 of 3

I'm using the TalkTalk settings. But that just determines how I get to you, not how you get to everyone else. As I've pointed out before, any problems with the old Pipex settings could be resolved by updating those settings to be the same as the TalkTalk ones in the TalkTalk DNS data.


However, that bounce does seem to be a one-off. I didn't get it when I sent a test message to my friend just now.

Hi gmlack, are you using the settings for sending or pipex ones? If the latter please change to the ones. Let us know if you're still getting bouncebacks.
