Can anyone help, please, with this problem? I use a laptop at a customer's site, and when I am there, my laptop is configured as if it were one of their own machines and is listed in their /etc/hosts; they do not run DNS. Their mailserver is running Microsoft Exchange(?); I can download mail with POP3 and am supposed to be able to upload mail with SMTP. However, in every configuration I have tried, including specifying the IP address directly in the "To:" address, sendmail defers the mail, saying that it is unable to resolve the reference.
/etc/nsswitch contains only "files"; the "dns" word is commented out. I have made sure that the SMTP server is listed in my /etc/hosts; this is the same host from which I successfully get mail with fetchmail (POP-3 protocol). -- Vote against SPAM: http://www.politik-digital.de/spam/ ======================================== Oliver Elphick [EMAIL PROTECTED] Isle of Wight http://www.lfix.co.uk/oliver PGP key from public servers; key ID 32B8FAA1 ======================================== "God is our refuge and strength, a very present help in trouble."
