Suddenly today I started receiving calls from my
Outlook and
Thunderbird users who are having problems sending messages.  They all
receive the “time-out” message communicating with the server. 
I checked my own outlook (2007) and sure enough same problem.
   
  SurgeMail
Version 5.0m-1, Built Oct 18 2010 21:02:04, Platform Linux (Surgeweb
Enabled)
   
  Surgeweb is working fine… no problems there.
  We have made no firewall changes.
   
  Last ditch effort… I changed the smtp port from
25 to 587
and my machine will now send.  If I switch back to port 25 I get the
time
outs.
   
  The only changes that have been made in the last
couple days
to the server were the installation of a digital certificate yesterday
morning. 
I don’t think this is anything to do with that since everything has
been
working until mid-morning today.
   
  From a command prompt I checked port 25 using
telnet and
this is what I get:
  220

  From a command prompt I checked port 587 using
telnet and
this is what I get:
  220 grady.k12.ga.us SurgeSMTP (Version 5.0m-1)

  Does
ANYONE have any ideas or thoughts on this?
