[CentOS] Evolution

When I set up the Evolution mail agent, I could find no way to change 
the outbound port from 25 to 587.  I have to do this due to port 25 
being blocked by the cable company.  Thunderbird is no problem.  Altho I 
don't particularly use Evolution as a mail agent, there are times when I 
might use it, but its worthless without being able to send mail out to 
my server.  Did I miss something in the options or setup or is there no 
provisions for changing the smtp port to another port?
