Did you set this up in Thunderbird or in your webmail?

Er, in Thunderbird I think, but it's not showing in Tools/message filters... Thanks for any help you can give. Mozpete

Usually, you set this up via webmail.

If you set it up in thunderbird, then you would of had to leave your computer on, logged into your User account, Thunderbird running and connected to the internet. Not exactly a very safe option if you are not at home with computer, hence why people set it up in webmail. You would have set up a Message filter and created a Template email for it to use. so if there is no Template email and no Message filter to disable in Thunderbird, then it is not Thunderbird, it is the server. Suggest you log on to webmail and check your settings.

Thanks for the help and info. Will check my webmail now. Cheers
