Hi I am trying to pass a variable with the hostname to the smtphost parameter of sendmail: <dtml-var standard_html_header> <dtml-sendmail smtphost="PARENTS[_.len(PARENTS)-1].getProperty('mail_smtphost')"> To: <dtml-var "PARENTS[_.len(PARENTS)-1].getProperty('mail_to')"> From: <dtml-var sendername> <<dtml-var senderaddress>> Subject: <dtml-var subject> <dtml-var comments> </dtml-sendmail> </dtml-let> <dtml-var standard_html_footer> This results in a host not found error. However, when I hardcode the smtphost like: <dtml-sendmail smtphost="192.168.0.20"> This works. I also tried (did not work): <dtml-let myhost="PARENTS[_.len(PARENTS)-1].getProperty('mail_smtphost')"> <dtml-var myhost> <dtml-sendmail smtphost=myhost> I am very sure the property is defined and returns the correct value (tested). What can I do ? Gijs
