If you are setting up a new service, system or piece of equipment, you may need to set an outgoing mail (SMTP) server to send automated emails. Examples include:

  • cloud hosted services, e.g MailChimp;
  • equipment monitoring software, e.g. freezer alarms;
  • hosted servers.

We provide three options, depending on your requirements. An explanation of the differences is provided below but please contact the ICT Service Desk if you are unsure which one to use.

Sending mail internally

Use automail.cc.ic.ac.uk to send automated email within the College network, unless you are configuring a Linux mail service, then use smarthost.cc.ic.ac.uk.

Internal email acc widget

automail.cc.ic.ac.uk

  • For internal use only. Not suitable for machines used off-site (e.g.  laptops).
  • Available only on port 25. Authentication and TLS are not required.
  • Errors are not generated at SMTP time.
  • Bounces are directed to the owner of the machine.

smarthost.cc.ic.ac.uk

  • For use by Linux mail services (e.g. Exim, Sendmail, etc.) to send machine mail (e.g. from root, cron, etc).
