Incoming mail going to wrong folder

[tinyf]

Can anyone advise, please.

I have mail from two accounts redirected to Thunderbird. Since a few days ago mail from my @gmail.com address has been delivered to my @blueyonder.co.uk address. Anyone know what might be happening.
Thanks

Moving to Thunderbird Support as this is not a question about Firefox.

Please clarify what you mean by "I have mail from two accounts redirected to Thunderbird". How are they redirected?
Do you have any Message Filters active in Thunderbird? http://kb.mozillazine.org/Filters_%28Thunderbird%29

They're forwarded from my Virgin Media account to Thunderbird, where I pick them up rather than go online to Virgin Media. I don't have any filters set up.

Have you checked the server settings for each account under Tools->Account Settings->Server Settings?
Have you checked the settings on the Gmail web mail page to see if there is any forwarding set up that might explain the issue?
