I can't answer this question, but I'd like to piggyback a related question (I think).
Background: I'm learning about email, procmail, postfix, pop servers, etc. I've become aware (I think) that if you have a "shell account" at your ISP you could potentially run Procmail on the ISP's machine, and filter mail (based on your rules) and discard it without ever downloading it to your machine. (This would at least save me some connect time or bandwidth, and others paying for connect time, some money.) Question: Is there a way to do something similar without having a "shell account" at your ISP. Or, does everybody with an account at an ISP have at least some sort of shell account, because your email address does represent a user account on the ISP's email server? And, if so, can you set up Procmail with your own rules there? Aside: I'm aware of tools like kshowmail that (and my ISP's webmail thingie), which let me look at the mail on my ISP's server and consider deleting stuff, but my ISP's webmail thingie is so slow it makes me believe I am not saving any bandwidth (and I know I'm not decreasing my connect time -- it's going up).
