SMTP on port 25 stores mails for the domain's accounts as Java reads them anew and tells a local sender of unknown recipients; POP3 on port 110 hands them out. The mailboxes are in the snapshot and go back into the project. EmailRun plays four stories over the network; MailCases feeds Java's workers without one (26 cases, de and en). 18 cases name Java bugs that the core does not take.
