I'm trying to set up an email address in qmail such that a unique identifier can be passed as part of the email address.
For example:
[email protected], [email protected], [email protected] would all go to the 'reply' user and be sent to the same shell script. Currently, email sent to [email protected] goes to the script and I pass the unique id in the subject or message body. Would be grateful for any suggestions. Thanks!
In a default qmail setup, you can do exactly what you suggest... anything following a dash is ignored for delivery purposes, so [email protected] will be processed by the .qmail-reply file, where you would presumably send the mail to your script and look at the address to obtain the identifier.
We use this for bounce tracking - if the email is to [email protected], and the sender is [email protected], then the from address is written this way:
And a script flags the address as no good.
EDIT:
I screwed this up a bit - I guess I'm rusty on qmail. The alias thing doesn't work by default as I stated above. To support extensions for [email protected], you need a .qmail-default file in ~bounce.
