[Bug] FTS invalid address parsing

[azurit]

Hi,

i found another bug in FTS while parsing  
quoted-printable/base64-encoded sender's name inside 'From' header  
(again, i was figuring out why some of messages cannot be searched).


Header: From: =?UTF-8?Q?A=2CB?= <t...@example.com>
Data send to Solr by Dovecot: <field name="from">A@, B  
&amp;lt;t...@example.com&amp;gt;</field>


Header: From: =?UTF-8?Q?A_B=2CC?= <t...@example.com>
Data send to Solr by Dovecot: <field name="from">A@</field>


Header: From: =?UTF-8?B?QSBCLEMK?= <t...@example.com>
Data send to Solr by Dovecot: <field name="from">A@</field>


Dovecot 2.2.27.
