[SLE] outbound pop with sendmail
Hi, I have a co-location machine setup, it sits behind a cisco router used as a firewall. There is a mail problem of sorts and the operators have setup a web-mail system for everyone on the subnet, rather than let everyone run pop on their machines. I CAN: --use cgi scripts to send out mail via sendmail --I can accept incoming mail, and retreive it thru the pop protocol I CANNOT: -- reply to mail downloaded thru pop, and reply to it, and have sendmail at my domain relay it properly. Where in sendmail.cf do I tell sendmail to accept mail from pop clients and forward them out, as normal isp's operate? Did this make sense? :-) Thanks -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/support/faq

No. Pop receives mail it doesn't send it. Are you saying the system won't relay? What exactly is the error message that sendmail is giving you?

The actual message is "host unreachable". What is being done is at the cisco router, which is intercepting all mail port requests and sending them to some web-based mail program they run. So I can only use mail in the local subnet I'm in, ie I have to ssh in and use Pine to get and send mail. Everything from the outside is blocked. The Webmail program they use is nice, and unlimited, but it is totally out of my control. The tech guy said that there was something in sendmail.cf that needed to be changed on my machine, but he wasn't sure how to implement it. Then once that sendmail.cf change was made, he could open up the cisco router to let mail port calls thru to my ethernet card. So I'm quite in the dark as to what is happening. I am looking at qmail as an alternative, as that is what everyone is talking about now. Do you think this is what "Carnivore" is all about? -- To unsubscribe send e-mail to suse-linux-e-unsubscribe@suse.com For additional commands send e-mail to suse-linux-e-help@suse.com Also check the FAQ at http://www.suse.com/support/faq

Okay I'm still confused. How is you changing your sendmail.cf going to matter to the router? The only thing I can think of is they don't want you leaving relay on. I was going to say maybe they want you to use the router has an outgoing mail server but since they are willing to open the ports up that doesn't make sense. The other thing is who sends you that error message? I'm guessing you are trying to send a message out and your internal machine can't get out? Or is it an external machine trying to get in?

Sounds like they want something particular done. Have them tell you what. Then we can figure out how.

If the ports are closed then it won't matter what's running on your end. I'm guessing they want to make sure you aren't an open relay but they should tell you that. FWIW if all they want is to make sure you aren't an open relay then I think all SuSE sendmail since 6.1 defaults to no relay.
