3.1.1. Running Services

AXIGEN is a modular server running either as integrated service server or with certain services inhibited.

When using AXIGEN as main mail server, it is recommended to run all services provided by AXIGEN - Processing, SMTP Incoming, SMTP Outgoing, POP3, IMAP, WebMail, WebAdmin, CLI, Log, Report, FTP Backup - in order to take full benefit of functionalities offered by the server. By default, when installing mail services the following services will be running: SMTP, IMAP, POP3, WebMail and WebAdmin. SMTP stands for all AXIGEN SMTP services: SMTP Incoming, SMTP Outgoing and Processing.

To see configuration options on this parameter see the Configure the Running Services section.

A similar option is available in WebAdmin at domain and account/mail list level with relevant choices for the respective level - see the Domains&Accounts section for configuration options.
