Chatter email 502 5.5.1 Unrecognized command Sending Error

Question

I have a Treo 680 (Rogers) that I have been successfully using Chatter email with for about 6 months (multiple email accounts).  No changes have been made in configuration however today when I try to send email messages I'm receiving a 502 5.5.1 Unrecognized command Sending Error message and can not send email messages on any accounts.  I can still receive however.   Any suggestions?

Hi Paul,
May you please guide me thru the SMTP configuration.
By the way, I tried to implement the APEX_MAIL and it's delivering the mails internally but not externally. When I check the Mail log all mails appear but when I check my yahoo account there's no mail delivered but in the internal mail there's mail delivered.
Here's my application level On Demand process code (On Demand: Run this application process when requested by a page process)DECLARE    l_id number;    l_index number;    l_vc_arr2    APEX_APPLICATION_GLOBAL.VC_ARR2;
BEGIN  l_id := APEX_MAIL.SEND(p_to => :P19_EMAIL,            
p_from => :P19_FROM,             
p_subj => :P19_SUBJECT,             
p_body => :P19_BODY); 
l_vc_arr2 := APEX_UTIL.STRING_TO_TABLE(:P92_IMAGE); 
FOR i_index IN 1..l_vc_arr2.count LOOP    
FOR c1 in  (select filename, photo, mimetype from employee_tb
      where emp_id = l_vc_arr2(i_index))
loop  APEX_MAIL.ADD_ATTACHMENT( p_mail_id    => l_id,                               
p_attachment => c1.photo,                               
p_filename   => c1.filename,                               
p_mime_type  => c1.mimetype);   
END LOOP c1; 
END LOOP i_index; 
COMMIT;END;
-- push the e-mail queue for immediate delivery:
begin
wwv_flow_mail.push_queue(
   P_SMTP_HOSTNAME => 'mail host',
   P_SMTP_PORTNO => '#'
end;Kind regards
