This seems to be a common problem, as I found a number of complaints about it on the web, but no solutions which seem to work for me. I have a small home network with a dedicated server running Debain 2.2 w/ kernel 2.4.1. I have qmail installed and working on the server - I can send and recieve mail over the internet if I'm logged in locally to the server. I'm now trying to get POP3 working so I can access mail from my other systems. I can not get checkpassword to authenticate my login. I can telnet into localhost port 110 and get the POP3 prompt but it denies my password everytime.
I have shadow passwords and PAM installed and am using checkpassword v0.90, which is supposed to work with shadow passwords and PAM. I found mention of setting options in the Makefile to enable this but as near as I can tell this referred to v0.8x and they no longer seem to be there in v0.90. Thanks in advance for any suggestions or hints on how to fix this.
