Incoming Email

1. Determine or create the user_identification_id and issue_id as follows.

   Incoming email will come to an email address either of the form service-user_identification_id-issue_id@whatever.com or just service@whatever.com.

   • Case 1: service-user_identification_id-issue_id@whatever.com

     Do a check to make sure that issue actually belongs to that user (check that issue_id and user_identification_id match in ec_customer_service_issues).

     • If so, just reopen the issue if it's closed.
     • If not, they've probably been messing with the numbers in the email address, so just treat it like Case 2.

   • Case 2: service@whatever.com
     1. Determine the email address from which it came. See if the email address belongs to a registered user of the system.
        • If so, see if there's a user_identification_id with that user_id (only grab the first one, if it exists, then flush the rest).
          • If so, great, we'll be using that user_identification_id later.
          • If not, get a new user_identification_id (using ec_user_ident_id_sequence) and create the user_identification record (insert into ec_user_identification (user_identification_id, date_added, user_id) values ($user_identification_id, sysdate, $user_id)).
        • If not, see if the email address belongs to a non-registered user with a past customer service record (i.e. there's a row in ec_user_identification with that email address; only grab the first one, if it exists, then flush the rest)
          • If so, great, we'll be using that user_identification_id later.
          • If not, insert a new row into ec_user_identification with user_identification_id, date_added, email, and, if you can regexp them out, first_names and last_name filled in.
        Now we have a user_identification_id to use.

     2. Create a customer service issue. Set the issue_id (you'll need it later) to ec_issue_id_sequence.nextval, and then insert into ec_customer_service_issues (issue_id, user_identification_id, open_date) values ($issue_id, $user_identification_id, sysdate).

2. Create a new interaction.

   Just generate an interaction_id with ec_interaction_id_sequence. Then insert into ec_customer_serv_interactions (interaction_id, user_identification_id, interaction_date, interaction_originator, interaction_type, interaction_headers) values ($interaction_id, $user_identification_id, sysdate, 'customer', 'email', [the headers from the email]).

3. Create a new action.

   insert into ec_customer_service_actions (action_id, issue_id, interaction_id, action_details) values (ec_action_id_sequence.nextval, $issue_id, $interaction_id, [the body of the email])
