Relay Outgoing SMTP Mail through Vertrauen
Your ISP restricts or blocks outbound connections to TCP port 25 so you are unable to have the Synchronet Mail Server perform Direct Delivery of email messages to public mail (SMTP) servers which require mail delivery on TCP port 25.
Some public mail services (e.g Gmail) reject email messages from your server due to a blocked/untrusted IP address or lack of a “SPF TXT” DNS record that authorizes mail to be sent from your mail server for your hostname.
Use Vertrauen's Synchronet Mail Server (on TCP port 587) to relay your outbound Internet mail.
- If you do not already have a QWK networking account on Vertrauen, create one.
- If running Synchronet Control Panel for Windows, shut it down.
RelayServer=mail.synchro.net RelayPort=587 RelayUsername=your BBS's QWK-ID RelayPassword=your QWKnet account password
Alternatively, if you using Synchronet Control Panel for Windows, you can use the SBBSCTRL:Mail->Configure menu option to make the configuration changes and then hit the 'OK' button:
Note: the “Use Relay Server” radio button must be checked on the “SendMail” tab for the “Relay” tab shown above to appear in the configuration dialog box.
Or... in SCFG v3.20+, in Servers->Mail Server->SendMail Thread...

This relay service can be terminated for one or all clients for any reason at any time. Most notably, if you send SPAM through Vertrauen, you will lose all access to Vertrauen's services, including this one. Your relayed mail messages are not private and there cannot be any expectation of privacy.
