As you can deduce from the title I am a member of Yougov and I use BTYahoo spamguard in email classic. Every once in a while I spot a message in the spam folder from Yougov and have to mark it as not spam.
This works for a few weeks, but doesn't permanently "stick" and I keep missing the invitations to take part in surveys
Is there any way I can white list these messages from firstname.lastname@example.org ?
Although I use the BTY Spamguard I do all of my email in Mozilla Thunderbird, so I'm only in the BTY email once a flood.
