Yes, but why is it coming from sourceforge, if someserver.suse.com would do this I would not have asked it.
Yet many (probably the vast majority of) people do not run an SMTP server which allows incoming connections as email comes via ISPs and POP3. The one is SuSE 8.0 does not listen on external interfaces out of the box - you have to enable it if you want, which is a good security measure.
I have my own domain and run a mailserver on it.
Well, true and i probably miss your point here, but it seems sourceforge is running an exim mailer that is configured to do what the exim folks call an "callout". This callout does exactly what GertJan asked for. I am not experienced with exim, so please do not ask me for details. I just did a small lookup in the exim-documentation and telnet'd to that host because somebody told me about this 'feature' some while ago. (reference: Exim-Specification, ch. 37.10, www.exim.org)
O.K. so it's probably a callout from sourceforge.net, because someone (probably Togun) with a sourceforge address is subscribed to the list. See also the answer from Togun below, although he didn't explain why sourceforge is doing this when I send something to the list, I'm not the one who is sending it to sourceforge. Also I fail to see the purpose of this check, for example I could send mail to a sourceforge address with from: valid address_adress@yahoo.com, then it's probably going to check the yahoo.com mailserver although the mail is not coming from there.

822 section 6.3 (which you have to abide by if you send and receive Email) states that you are required to have a postmaster mailbox that is routed to the person responsible for mail (http://www.rfc822.com/).
Yes, but I'm not the one who is sending the mail to sourceforge, suselist does that. Imagine every mailserver is going to do this and there are a 1000 subscribers to a list, then if you sent a message to the list you immediatly get 1000 connections to your mailserver, I don't think thats how it's supposed to work. So either the check is broken or my assumption is wrong. -- GertJan
