[gentoo-user] Re: /etc/resolv.conf and return mail
I forgot to say that mail between espersunited.com users works fine. As I said, I've had this problem for a few days and I previously thought that the messages simply weren't being sent from the message queue.

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, What is the error message you talk about? Are you running your own mailserver internally, or trying to post to your ISP's SMTP? It looks like you mean your own, but before passing judgement could you confirm? .. but I cannot telnet to their port 25. If it's your own mailserver, is it trying to post directly to whomever you send it to, or routing through your ISP's SMTP? ~ Maybe your ISP has blocked outgoing port 25 (may have been several spammers / hacked_computers_used_by_spammers reported to you ISP from it's own network)? Does 192.168.1.1 run it's own DNS? Greetings Ralph Michael Sullivan wrote: I forgot to say that mail between espersunited.com users works fine.

Re: [gentoo-user] Re: /etc/resolv.conf and return mail
The error message is Warning: Could Not Send Message For Past Four Hours. It says that it could not connect to the server it's trying to deliver the mail to and that it will keep trying for the next week. I am using my own mail server. I do not wish to use CableOne's smtp server because I consider them to be incompetent. My Linksys router is set to obtain everything automatically from the cable modem. --- Ralph Slooten [EMAIL PROTECTED] wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, What is the error message you talk about?

Because: - you can ping by name to the outside mail server, so network connectivity and DNS setup is OK. - you cannot telnet its port 25, so this is administratively prohibited. Same thing applies for your mail server. You wont be able to do anything against it on your own side, except for writing harsh emails to your ISP... Only exception would be a misconfigured firewall on your side, but i don't suspect so. Well, and luckily they didn't block incoming SMTP, that's at least something;-) Maybe you have some internet server at hand that you could use to set up your own outgoing relay server? It could listen on a port != 25. HWH -- gentoo-user@gentoo.org mailing list
