Noosfero email setup

If you know mail systems well, you just need to make sure that the local MTA, listening on localhost:25, is able to deliver e-mails to the internet. Any mail server will do it. You can stop reading now.

If you are not an email specialist, then follow the instructions below. We suggest that you use the Postfix mail server, since it is easy to configure and very reliable. Just follow the instructions below.

  • General type of mail configuration: Internet with smarthost
  • System mail name: the name of your domain, e.g. ""
  • SMTP relay host:

Please note that this should be your last option, since contacting an external SMTP server directly may slow down your Noosfero application server. To configure Noosfero to send e-mails through an external SMTP server, follow the instructions on
