facing recipient_bcc_map regex / pcre issue

[jayesh shinde]

Hi ,

I have live mail archival server and now created the backup of the same.
For this I am taking bcc copy from mailserver  on which 
postfix-2.10.0-1.el6.x86_64 running

recipient_bcc_maps = pcre:/etc/postfix/bcc_maps
[root@jayesh ~]# cat  /etc/postfix/bcc_maps

/^(.*)@(.*)$/ $1!$2...@archive.mydomain.com


Above is working fine for me.   Now for creating another copy of mail 
for backup archival server I modified the bcc_maps as follows.
but by this the recipient email id is generating with " "

recipient_bcc_maps = pcre:/etc/postfix/bcc_maps

[root@jayesh ~]# cat  /etc/postfix/bcc_maps
/^(.*)@(.*)$/ $1!$2...@archive.mydomain.com,$1!$2...@archivebkp.mydomain.com 
<mailto:$1%21$2...@archivebkp.clientdomain.com>

[root@jayesh ~]# mailq
-Queue ID- --Size-- ----Arrival Time---- -Sender/Recipient-------
BCC7E5FD6B* 569 Thu Nov 6 16:39:58 mailf...@senderdomain.com 
<mailto:idcale...@netcore.co.in>
*"*netcal5!demo.test....@archive.mydomain.com 
<mailto:netcal5%21demo.nstest....@archive.clientdomain.com>,netcal5!demo.test.com*"*@archivebkp.mydomain.com

I am getting same result with  pcre & regexp

Can any one suggest the correct pcre / regexp format or workaround 
solution  , so that " " will not come for bcc recipient ?
