Incoming mail is fine. from my box: %telnet snybufaf 25 Trying 136.183.139.17... telnet: Unable to connect to remote host: Connection refused from this box, with a similar setup (different ISP): gregory %telnet 136.183.139.17 25 Trying 136.183.139.17... Connected to 136.183.139.17. Escape character is '^]'. 220 snybufaf Sendmail 5.65v3.2 (1.1.3.6) Mon, 25 May 1998 09:49:36 -0400 Telnet (to port 23), ftp, http, finger etc. to machines rejecting a port 25 connection works normally. Neither one of these machines will reverse lookup, and the only difference between my setup here and my setup at work is that I'm going through sprint now: I was using a .dyn.ml.org address at work (a college). > It may be, however, that the host's sendmail still thinks that it has > the name and IPA that it has at work.

None of these hosts reject the machine I'm on now, and as far as I can tell there is no difference between the configuration of this one and mine. Like I said, the only difference between my setup a few days ago and my setup now is that I'm using sprint for my internet connection. I'm beginning to wonder if they are using anti-spam measures that prevent me from sending outgoing mail from my box. > -- > Is the true purpose of Unix its use, or its administration? > Dig the sig :) To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
