[xwiki-users] Links in mail notification messages.

Hello. I've set up Tomcat, MySQL and Xwiki on one of my servers called White (white.mydomain.ru). Xwiki is reachable at http://white.mydomain.ru:8080/wiki Then I've set up Apache on my main server (mail.mydomain.ru) as proxy. Now my Xwiki instance is reachable at http://mail.mydomain.ru/wiki and this link is main for end users. Everything is ok, but notification messages contain links to white.mydomain.ru:8080/wiki, which is not accessbile from internet (only from local network). How can I change it? How to force Xwiki, to write links to mail.mydomain.ru/wiki, instead of white.mydomain.ru:8080/wiki? Thanks in advance. Dmitriy Nikolaev
