Run the built-in check, in the ProBoard folder:
PBMailer -cfg PBMAILER.CFG -test
It reads your settings and reports what it finds. Then check the link's host and port, your firewall, and that BinkP (24554) is open if others call you. See FidoNet mail.
It has not been tossed. Run a toss from the Mailer / Tosser menu in PBDispatch. A message area must exist for an echo before PBToss can put mail in it. See FidoNet mail.
PBMigrate adds an echo to PBToss only if a matching message area already exists. Create the areas with Import from FastEcho… on the Message Areas screen. See Importing FastEcho and Internet Rex settings.
Check the node's settings in PBQWK.CFG and the hub's address and port. The hub and PBFtp both default to port 21. See PBLink.
