Not sure how to file this, so my apologies. the pop3login program crashes without calling courier-authlib, but I suspect its an underlying problem with a different package. This is required for pop3 clients to successfully connect. To recreate, 1) networkless install of gentoo-2008.0-beta1 2) emerge courier-imap 3) create a test account 4) change /etc/courier/authlib/authdaemonrc to use pam authentication localhost ~ # pop3login x x DEBUG: Connection, ip=[127.0.0.1] +OK Hello there. user fergus +OK Password required. pass f Segmentation fault authtest shows that the authentication method is Ok /var/log/messages has entries for authlib when using authtest but not when using pop3login /var/log/messages Apr 10 16:32:55 localhost pop3login[12049]: segfault at 00000000 eip b7e83d09 esp bf8164a8 error 4 I'm not sure exactly which component is causing this. The 2007.0 build was fine, but upgrading the 2007.0 this week, and coincidently upgrading imap from 4.0.6 to 4.1.x resulted in this problem. I've tried downgrading courier-imap to 4.0.6 but the problem still exists, so it looks like some component that courier-imap depends on traceback on the original system where the problem started reboot system boot 2.6.23-gentoo-r3 Sun Apr 6 10:36 /var/log/messages Apr 9 09:36:07 gw pop3d: LOGIN, user=m000001, ip=[::ffff:10.1.1.145] Apr 9 09:36:09 gw pop3d: LOGOUT, user=m000001, ip=[::ffff:10.1.1.145], top=0, retr=4086, time=2 so ok, then failures begin after reboot system boot 2.6.23-gentoo-r3 Wed Apr 9 11:29 (03:39) Apr 9 11:36:31 x1-6-00-02-44-49-04-70 pop3d: Connection, ip=[::ffff:10.1.1.145] Apr 9 11:36:31 x1-6-00-02-44-49-04-70 pop3d: LOGIN FAILED, user=m000001, ip=[::ffff:10.1.1.145] Apr 9 11:36:31 x1-6-00-02-44-49-04-70 pop3d: authentication error: Input/output error note the hostname change as well.

It seems that calling pop3login on the command line always seg faults. I think that some other issue was at work.
