[xmail] SMTP routing based on source email address ??
This is probably a good one for Davide. I have a customer that wants to route certain outgoing emails though a different internet link (a faster link) for certain users of a domain. It gets better !! The two internet links are connected to the same firewall, so at the IP layer the firewall (a packet filtering only firewall) cannot distinguish between the two user groups. My thought was that I could have two instances of xmail running bound to different IP addresses, and route the priority users through the second xmail, the firewall would see a different source IP and be able to route the traffic accordingly. The problem is, how to route at the application layer, certain users to the second xmail. All users have the same internet domain. I'm not concerned with incomming mail, it can come in through the first xmail server. Alternately if anyone has other options for achieving the same end, or other products that can route email based on source email address, I'd really like to hear about them.

create a second domain such as fuckingidiots.thedomain.com Mail will get there. Either use the slow (what is it? DSL? I've used ISDN to connect 100 people to the internet as well as the mail server for those 100 people) link for everyone or if the emails have to get there faster then use the fast link for all emails. -Mensaje original- De: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]En nombre de Rob Arends Enviado el: Sunday, February 16, 2003 10:42 PM Para: XMail mailing list Asunto: [xmail] SMTP routing based on source email address ??

Oh, I actually have an idea that should work :) Since this is behind a firewall I can assume that you dont need any protection from spammers Just setup Xmail runing on different ports/Ip/machine/etc just as an open relay -Mensaje original- De: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]En nombre de Rob Arends Enviado el: Sunday, February 16, 2003 10:42 PM Para: XMail mailing list Asunto: [xmail] SMTP routing based on source email address ??

I didn't mention that the existing email server is Novell's Groupwise. The users don't have control over the outgoing smtp server to send email. I was thinking of GroupWise using xmail as a smart host, to drop all outgoing mail, Xmail have the smarts to look at the source email address via a mailproc perhaps and if it is not one of the priority users, then send the mail, or if it is from one of the priority users then relay it to another smtp relay (doesn't have to be xmail). If It can't be done at the application layer, perhaps it can be done at the file level. Davide, if a mailrpoc was to identify an email to be relayed, could it copy the email file to the input queue of another xmail server and return an exitcode that effectively blocks or deletes the email on xmail server one. The second Xmail server reads the in queue and sends it out. In theory would this work ?? What dir could I drop a properly formatted file into? Rob :-) You can't route based on the sender, you can only route for destination ( smtpfwd.tab ). And it's domain based, not user based. You cannot run two instances of XMail on the same machine also. You have to setup another XMail machine and you have to tell those users to use such machine as SMTP server. You'll configure this machine by only having custom domains ( the ones that you handle ) that smtprelay to you main ( POP3 ) machine. At this point you can setup source routing on your firewall. - Davide - - To unsubscribe from this list: send the line unsubscribe xmail in the body of a message to [EMAIL PROTECTED] For general help: send the line help in the body of a message to [EMAIL PROTECTED]
[xmail] Re: still a problem with psync
Davide Thanks for your analysis. I'd appreciate psync to just kill syntactical wrong messages. It's of no help if I find out by chance that a message delivery has stalled some weeks ago. The message content may certainly be outdatet by the moment of discovery. Usually it's spam anyway... Could this cleaning feature be a future improvement? Or, could such mail just be passed to the psync account? I wouldn't have seen this problem if I hadn't installed SpamPal (which I appreciate much) as a spam marker proxy with bayesian filter plugin running on it. I was just wondering a little that the same messages were processed by the bayesian filter again and again and again and again and .
