Hi All I would be really grateful if someone could help with a difficulty I've run into with the Courier ESMTP server.
I am working through a new installation of Courier on a machine that is to be later moved to an operational environment. I have worked through getting the authentication bit working with an LDAP backend, which was easier than I expected, and have demonstrated IMAP working by sending messages locally using sendmail. I can pick these up with a remote mail client. ESMTP is being difficult however. I can connect to it both locally and remotely by telnet to port 25, and it identifies itself correctly with the banner "220 hta21.trinity.asn.au ESMTP", but the only command it seems to accept is QUIT. The commands I have tried are ELHO, HELO, DATA and HELP. The response is "502 ESMTP command error" (command not implemented), with a similar entry in the maillog (nothing in the syslog). The firewall is turned off, and in any case this behaviour occurs even when accessed from the local machine. Can anyone identify a likely cause of this behaviour? I built the Courier source using the Fedora rpm utility to create a bunch of rpms and they seemed to install with no issues. The installation uses Fedora 3 and the latest Courier source as of a few days ago from the Courier site. The configuration files are basically unchanged except of course for the authentication ones, and that works fine. I have set the smtpaccess file to open up localhost and the LAN subnet, and telnet does connect in both instances. The esmptd config file is unchanged from the default except for the ESMTPDSTART=YES line. Emails sent remotely are being rejected with "Connection refused", but I haven't pursued this deeply in view of the above behaviour. cheers, Ken -- Ken Sarkies <[EMAIL PROTECTED]> -- Ken Sarkies <[EMAIL PROTECTED]> ------------------------------------------------------- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.
