I apologise striaght away for the completly off topic mail, but I'm desparate!
I am having problems with return receipts from our users here at work. When someone requests a return receipt and I click okay, I get a Mailer-Daemon with the error: >>> MAIL From:<@@fransmaas.co.uk> SIZE=2583 <<< 501 <@@fransmaas.co.uk>: domain missing or malformed For some reason it appears that the return receipt is not picking my email address as being the "From:" address and the mail server (Sun box, Solaris 2.6) is substituting the "From:<>" with "From:<@@fransmaas.co.uk>" When I have a look at the sendmail config (sendmail.cf) I can find: # handle "from:<>" special case R$*<>$* $@@ turn into magic token Has this got anything to do with the problem? Please be aware that my sendmail knowledge is very poor :( Thanks in advance for any help. Ewen
