How do I prevent GMS v2 or v3 acting as an open relay?
How do I prevent acting as an open relay for spammers?
The last version of GMS v3 is protected from open relay by default. Therefore GMS will not be relaying an email unless you make it do so.
If you have a version prior to 3.03E (or 3.03.0018), you have several options:
1. Upgrade to the latest version of Gordano software.
2. Upgrade to 3.03E. A free download can be obtained from ftp.gordano.com.
