indimail-services - Overview of IndiMail Services
/service/*
indimail uses various services configured to run under svscan(8) and supervise(8). These services provide SMTP, SMTPS, IMAP, IMAPS, POP3, POP3S and mail transfer protocols. Apart from the services which provide the basic protocols, there are few ancillary services needed to run these protocols.
Detailed below are the services configured for indimail. Each service name is also a directory in /service, which has a file named run and log/run.
