Sometimes I can't find what I need with Google. Sometimes (like for this) I find so much information I just end up confused...
I have a Postfix server (which I set up using a collection of how-to's so can't really claim to know how it works!) which collects mail, runs it through dspam (to remove spam) and amavis (to remove viruses) before dropping mail into a local POP3 mailbox or forwarding it to an external email address (eg hotmail or similar). What I want to add is to allow it to collect mail for certain domains for forwarding to another SMTP server (the server to use depends on the email domain and is not held in MX records). (Typically it will deliver mail directly into an Exchange server at a customer site without that customer's ADSL static IP being published in MX records.) I've found secondary MX information (where Postfix would look up the destination based on DNS) but haven't found a good enough query to find information about setting a destination SMTP server per email domain. Also: I have to handle the destination server being offline for periods of a few days. I would assume it will retry automatically for a short period before returning mail undelivered; I need to make sure that period is going to be long enough (ie configurable). -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0845 45 89 555 Registered in England (0456 0902) at 13 Clarke Rd, Milton Keynes, MK1 1LG _______________________________________________ Peterboro mailing list [email protected] https://mailman.lug.org.uk/mailman/listinfo/peterboro
