Some isp's block incoming connects on 25. *** *** FYI *** FreeServe, Energis & Demon are doing just this. I work in a company who supports a FreeBSD based Internet Appliance & during the last fortnight, we have had to change the way a lot of our customers send their email. Previously being able to send through our servers (to have the emails virus-scanned). FreeServe made a policy decision, to block ALL port 25 traffic accross their network. I believe their hand was forced by Energis, but it would have been a good idea to mention it to their customers! Dial-up accounts are blocked from port 25 unless the destination is their own SMTP server, (it has been made to look as if the other servers are refusing connections. ADSL accounts have the port 25 requests "forwarded" to the FreeServe SMPT server which is most disconcerting when trying to diagnose! I am informed that this kind of action is due to AOL getting uppety with Demon & forcing them to restrict their network simliarly, due to AOL customers being SPAMMED by mail that appears to originate from Demon Networks... BT is doing similar to their dynamic IP customers... Thought this might interest a few of you ;-) Chris xx intY has scanned this email for all known viruses (www.inty.com) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
