Re: Sender-Dependent Aliases
Ok, cool, thanks everyone. I checked out qpsmtpd but couldn't really find resources explaining how to do address rewriting; maybe I'm supposed to write my own perl script to do it. (I don't know perl, but if this is actually an easy solution and you can link me to somewhere that explains how to do it or something similar, I'd definitely be interested.) Writing a procmail recipe looks pretty simple, so that might be good. One concern with the procmail solution is that I'm going to be programmatically adding users to Mailman mailing lists. It would seem, therefore, that I would need to alter the procmailrc file programmatically too. This is easily accomplished, but I wonder if this isn't a very robust solution. I'd rather be adding entries to a database, for instance, than altering a file. I'm worried about how well a solution that relies on writing to a file will scale, as well as whether I'm going to run into concurrency problems if multiple processes try to write the file simultaneously. I'm sure you all have much more experience writing software than I do, so your advice would be appreciated. Thanks!

Re: Sender-Dependent Aliases
Cool, thanks for the response. I'm in the process of setting this up right now, but while I do that, I have a couple quick questions: 1) This seems like it might redirect *all* mail coming from from_address@domain to new_to_address@anotherdomain. That's not quite what I want. In my first example, pers...@gmail.com might be subscribed to more than one mailing list, so I need to redirect based both on the sender and the mailing list. I can see that this wasn't clear from my first email, so sorry about that. To be absolutely clear, an email from pers...@gmail.com to mail...@example.com should go to mailm...@lists.example.com, an email from pers...@gmail.com to another_l...@example.com should go to another_li...@lists.example.com mailm...@lists.example.com, an email from pers...@gmail.com to mail...@example.com should go to mailm...@lists.example.com 2) I assume it's possible to enter the redirect mappings into a mysql database directly, rather than write the mapping in a file, right?
