I have searched around about sendmail tag problems on the list and have found similar answers to my question. However none of them work. I have used this syntax <dtml-sendmail mailhost="MailHost"> To: <<dtml-var recipient>> From: <me@mydomain.com> Subject: <Whatever> body.... </dtml-sendmail> I pay close attention to not having any whitespace before the To: and From: headers. I receive this error from multiple SMTP hosts: 503 must have sender and recipient first I can send an email with this syntax: <dtml-sendmail mailhost="MailHost" mailto="you@yourdomain.com" mailfrom="me@mydomain.com"> body... </dtml-sendmail> The problem is, I have to put in the recipient by hand. This method is supposed to email a recipient after filling out a form so the recipient has to be a variable. When I try using <dtml-var recipient> or &dtml-recipient; or _[recipient] I still have errors or the SMTP log shows that the variable does not get evaluated and shows up as a string of <&dtml-recipient;> as being the recipient in the SMTP header. Is this a bug? Is there something else I could try? TIA Scott B.
