Hello, I have searched the archives, the web and IBM and have found bits of information here and there but eventually all these bits of information have led to totally confusing me. First of all I am not very knowledgeable in the Host Name and DNS area. I am trying to configure an AS400 to send email to an in house exchange server. I think I have everything defined correctly but when I start the TCP server *SMTP it does not start and I get an error (in the joblog) Cannot resolve Host Name information (or something close to that) I think the problem I have is in entering the Host name (the more I read the more confused I get) I know there are only about 4 or 5 steps to do (and I have done it in the past) Can someone explain the steps in "simpleton" terms. I have done the following: 1) I have the IP address (internal) and the host name of the SMTP mail server. (someone gave these to me so I assume they are correct) I can ping them successfully 2) I added a Host Table entry for the IP address and the Host name for the SMTP server. 3) I did CHGSMTPA MAILROUTER(the host name from step 2) AUTISTART(*YES) FIREWALL(*YES) 4) I added a directory entry for INTERNET SMTPRTE SYSNAME(INTERNET) PREFADR(NETUSRID *IBM ATCONTXT) 5) I added a directory entry for myself and used F19 to Change name for SMTP If my email address is ALLEN@xxxxxxxxxxxx On this screen I enter the first part of my email address ALLEN and for the SMTP domain I enter the last part of me email address tgsdcorp.com (I believe this is only used for my return email address correct?) 6) Then I execute the CHGDSTA SMTPRTE(INTERNET SMTPRTE) 7) During this process I also looked at our TCP/IP Domain information (CHGTCPDMN) and I am not sure what this should be (maybe I should stop looking at stuff) The Host name here is our AS400 serial number and the domain name is our corporate domain name . Can anyone explain what I may have done wrong (in simple terms) The more I look at these parameters the more confusing it sounds. When I did this in the past I just followed the steps and it worked the first time. Thanks in advance for bearing with me on this. Allen
