58 Chapter 2 Mail Service Maintenance
Holding Outbound Mail Service
You can prevent the mail service from sending new outgoing mail. You could do this to
isolate a problem, or to prevent conflicts with another mail service running on your
network. Furthermore, you could use this to stop virus propagation or spam relay
originating with your server.
Holding the mail service isn’t the same as disabling the SMTP service. Disabling would
prevent all user connections for outgoing mail, while holding outbound mail service
queues the mail for later sending. All mail is held in the outbound mail queue for
inspection or deletion until you stop the hold.
To hold outbound mail:
1 In Server Admin, select Mail in the Computers & Services pane.
2 Click Settings.
3 Select the General tab.
4 Click Hold Outbound Mail.
5 Click Save.
Blocking Inbound Mail Connections
You can prevent the mail service from receiving new inbound mail from external
servers. You could do this to isolate a problem, or to prevent conflicts with another mail
service running on your network. Furthermore, you could use this to stop virus
propagation or spam relay originating from external servers.
Blocking the inbound mail service isn’t the same thing as disabling the SMTP service.
Disabling would prevent all queued mail from being sent out, while blocking inbound
mail merely stops accepting any connections to add new mail to the queue. All
attempted mail deliveries are bounced and returned to sender.
To block inbound connections:
1 In Server Admin, select Mail in the Computers & Services pane.
2 Click Settings.
3 Select the General tab.
4 Click Block Inbound Connections.
5 Click Save.
