[Evolution] email address change for recipient name with dot

["salahuddin pasha (salahuddin66)" <salahuddin66 gmail com>]

I am having problem to sent mail to the users, who is having user name 
with dot.

Address change after/while evolution sent the mail and I get a failure 
notice.

example: U. Test <email abc c>  --->  U. T <est email abc c>


The changing patten is almost same for all the recipient users name with 
dot.
