I am attempting to use the freeware version of Netmail/3000, with a view to 'mail-enabling' some of our 3000-based systems, but I am running into problems as described below - help would be much appreciated. We intend to use a 'trusted gateway', since our organisation already has (internet) email up and running. Netmail is submitting messages OK to our trusted gateway, but they are being bounced back with errors such as the following: ----- Transcript of session follows ----- While talking to mailgate1.uea.ac.uk: >>> RCPT To:<<@139.222.130.1:[log in to unmask]>><<< 550 Unknown domain '139.222.130.1' 550 <<@139.222.130.1:[log in to unmask]>>... User unknown As you can see, the address [log in to unmask] has been preceeded by the string [log in to unmask]:' That IP address is that of an smpt server machine close to the actual mailgate that we are specifying (The IP address of the mailgate is 139.222.230.1). I have tried many different combinations of different mailgates and DNS servers within the university, but get similar (though not identical) results each time. The 'To' address is always preceeded by an '@' followed by IP address and a colon, and the mailgate, which expects just an email address (e.g. [log in to unmask]) and rejects it. (The mailgate is a Sun Sparc 1000e running Solaris 2.4, with the mail software being pp from Nexor.) Have other people experienced this problem - is there a known solution?
