Mail servers
In order for JIRA to communicate with e-mails, you need to configure or register your mail servers in JIRA. There are two types of mail servers you need to configure:
Outgoing: This is used by JIRA to send e-mails out to users. JIRA supports SMTP mail servers.
Incoming: This is used by JIRA to retrieve e-mails from users. JIRA supports POP or IMAP servers.
We will start with outgoing mail servers first to see how we can configure JIRA to send e-mails to users as well as customize the e-mail contents.
