Looks like the receiving system (93.95.216.141) doesn't like what your server is providing as the parameter to the helo/ehlo verb. To avoid problems here, make sure the following are true. 1. The parameter is a valid host name. The default for courier is to use the value of the "me" setting. You can edit that by looking in your courier configuration directory, /etc/courier on my system but maybe different on your's. You'll need to place the fqdn of your machine into /etc/courier/me, and depending on your system you may also need to place a host name in /etc/courier/esmtphelo. This will depend on exactly how your reverse dns works and how you have your server configured. 2. Make sure that the parameter being provided in the helo/ehlo verb is the same as what a reverse dns look up on the address of the host would resolve to. Not all machines check this, but they're starting to do it more often and you can have mail rejected if you don't meet this condition. It looks like as long as you meet condition 1, that is, a valid host name is provided in the helo/ehlo verb, the server you're trying to deliver mail to will accept your mail. But meet 1 and 2 if at all possible. You'll avoid future problems that way. - -- Those of you who think they know everything are very annoying to those of us who actually do. Joseph C.
