Looks like the same as T-Online is doing: The MXs are not reachable from "inside". Possible solutions: - use comcast's smarthost (smtp.comcast.net?) for outgoing mail. The easiest and probably best way, as your IP (69.250.247.7) is blocke by many mailservers. - use comcast's smarthost only for comcast domains. Easy if the list is constant (manualroute, domains, route_data), a little tricky if not (condition with MX lookup). You could also forge the addresses of the MXs to the smarthost's, but that's kludgy. -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
