Dear Sir,

i am using Email Option in my Application mail are send Successfully but all mail are sent from info@abc.com

DECLARE

l_id number;
to_add varchar2(1000):=:P1_TO; 
from_add varchar2(1000);
l_body varchar2(4000):=:P1_DESCRIPTION;
l_sub varchar2(1000):=:P1_SUBJECT;

BEGIN

   select email_id into from_add from user_master where user_id=:app_user;  

   l_id:=APEX_MAIL.SEND(
        p_to        => to_add, -- change to your email address
        p_from      => from_add,
        p_body      => l_body,
        P_subj      => l_sub);

         

  COMMIT;
apex_mail.push_queue(
P_SMTP_HOSTNAME => '102.111.0.9',
P_SMTP_PORTNO => 25);
commit; 

END;

select email_id into from_add from user_master where user_id=:app_user;
