Every time I send an email to a particular person, it fails to send. Why?? only happends to this one address.
Every time I send this person an email, it is returned as "Mail Delivery. Is this person blocked? Is the problem on my side or her side? Here is a shot of the failed delivery:
SMTP error from remote mail server after end of data:

Diagnostic-Code: smtp; 550-DKIM: encountered the following problem validating fbcinfo.org:
550 pubkey_unavailable
Help!

It is a problem between your email provider and the recipients email provider. Talk to your email provider. This has got nothing to do with Thunderbird.
