Acting as outgoing SMTP for customers with dynamic IPs without becoming an open relay
Hello, We are finally faced with the following situation: We have some customers who need to be able to use our mail server as their outgoing SMTP server (running Postfix). They are on dynamic IPs, so we can't just add one or two IPs to the relay configuration ($mynetworks). To make matters even worse, they really should be able to use our mail server to send from their laptops when traveling, and of course there's no way to know before hand what net block they're going to be on while traveling around the world. We cannot just open up wide and become an open relay. So , hopefully other people on this list have run into similar situations. What is the best solution for this? What have the rest of y'all done? My boss said he'd hear of packages that authenticate you for relaying when you successfully check your pop3. Currently I'm running Solid-pop3d for virtual user/virtual domain support, so I'm not sure how that will work. Any advise is appreciated, especially the Voice of Experience:-) TIA! ---------------------------------------------------- Jonathan Wilson System Administrator Cedar Creek Software http://www.cedarcreeksoftware.com Central Texas IT http://www.centraltexasit.com

I think this is what you want. I haven't tried it but it sounds right. http://www.sendmail.org/~ca/email/auth.html Nick
Hi, http://www.davideous.com/smtp-poplock/ should do the job for you. It was written with qmail in mind, but will work with pretty much any server (apparently). If you want any more info on qmail, let me know or go to qmail.plig.org. I've been running it for a while an am really happy with it. Cheers, Iain

Sounds like /usr/bin/X11R6/bin/comanche is a script written in some tcl dialect (itcl ??). The first action of the script is to call the interpreter. You will find a line like #!/usr/bin/itkwish at the top of the script. The fact that it doesn't find the interpreter can mean two things : - It is not installed --> install it (should be on the CDs) - It is installed in a different location --> modify the top line of the script such that it points to the right location or create a link from /usr/bin/tkwish to the right location (maybe better, other executables in the comanche package might look for itkwish in the same place. If you got the program from the SuSE CDs, inform them on feedback@suse.de, so they can fix it.
