Now pop3 again...

1. I run agent

2. I copy my correct config to = /mnt/auth and the=20 correct directories apear

3. I run upas/fs -f=20 /pop/mailserver/user

3. First , I "got no APOP hdr from = server" , I=20 commented out that section that didnt allow plaintext

3. retry upas/fs

4. "authentication agent failed", = "if((fd =3D=20 open(buf, ORDWR)) < 0)" fails.

5. agent wites by default r r r but the = open call=20 wants something else , so I changed the permissions in = agent.c.

6 rerun agent , copy config , = permissions=20 changed.

7. still "authentication agent=20 failed"..

so now what ?

/Michael=20 Grunditz

While agent lets you call it "pop" or "pop3" (or whatever you like) the sample config file uses "pop", and it seemed more consistent to have "pop" or "apop", not "pop3" or "apop".
