Hey, thanks for the quick response and suggestions. I’ll just work on pop3 for now. It appears from wireshark the error I need to investigate is…: “POP Response: -ERR Unknown AUTHORIZATION state commandâ€
Here’s the complete sequence of communication between a XP windows client and a Solaris 10 mail server (pike) running the pop3 service listening on port 110.
TCP pop3 > 2205 [sYN, ACK] Seq=0 Ack=1 win=49640 Len=0 Mss=1460
TCP 2205 > pop3 [ACK] Seq=1 Ack=1 win=64240 len=0
POP response: +OK POP3 pike 2006e.96 Server ready
POP Request: USER cal
TCP pop3 > 2205 [Ack] Seqs=38 Ack=13 win=49640 Len=0
POP Response: -ERR Unknown AUTHORIZATION state command
As you can see, pike is listening on port 110 and acknowledges readiness for communication; however, the login fails with proven login and passwords.
Any insight into this error message…
“POP Response: -ERR Unknown AUTHORIZATION state commandâ€
...other than an incorrect login/password being issued?
Thanks.
