Email addresses on exotic TLDs won't be extracted

[jaromil]

Despite its compliancy with RFC822 and RFC2047 our fetchaddr.c email address parser won't validate emails that have a long TLD, for instance .service or .equipment.

This can be reproduced by running the extract command on a mail containing such addresses in From: and/or To: and/or Cc: fields.

(more in general, I'm wondering how many other email clients are affected by this and if the RFCs would need an update...)
