If you have inbound mail, you should have a static IP address; any ISP selling static IP addresses should be willing to remove the inbound port 25 block once you confirm that you really are running a mail-server. If you're in NL, then there should be a few decent ISPs around who'll do this. Here in the USA, I'm stuck with Comcast (no DSL available at home) which is part of why I still have a colo box in NL. If the ISP is filtering inbound SYN, then you could use ssh with port-forwarding and a session which is kept alive at all times. If you have more than minimal guest access to a colocated system (ie, it's yours to do with as you will) then you could set up IMAP on that system and turn your home MTA setup into a satellite service, smarthosting via your own box. Then you can travel and not be dependent upon your home connection being up; given the quality of service that seems to be common with those ISPs who filter ports without exceptions, this might well be much safer. mvg, -Phil -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
