A little bit more information. I have checked the system log and found the following:
re pop3 (telnet host 110) Nov 22 15:14:58 jwilde-solaris ipop3d[14406]: [ID 806292 mail.debug] pop3 service init from 192.168.11.154 Nov 22 15:14:58 jwilde-solaris ipop3d[14406]: [ID 116098 mail.info] Command stream end of file while reading line user=??? host=jwilde.glocalnet.com [192.168.11.154] re imap (telnet host 143) Nov 22 15:52:02 jwilde-solaris imapd[14432]: [ID 806292 mail.debug] imap service init from 192.168.11.154 Nov 22 15:53:21 jwilde-solaris imapd[14432]: [ID 516645 mail.info] Missing command before authentication host=jwilde.glocalnet.com [192.168.11.154] above line produced from LOGIN james password after telnetting to the host Nov 22 15:55:11 jwilde-solaris imapd[14432]: [ID 985434 mail.info] Command stream end of file, while flushing line user=james host=jwilde.glocalnet.com [192.168.11.154] above line produced from a001 LOGIN james password. I got the a001 - presumably some kind of session number - from rfc 2060 It appears that ipop3d and imapd are having a problem reading the input. Grateful for any tips. mvh/regards James
