Thanks, that did the trick. Now I only have to find out how to let sendmail fil in my email address for me. At the moment no server wants to except my email as there is no email address in the "from" field. Take care, Rynhardt -- original message -- Subject: Re: email problem From: Willem van der Walt <wvdwalt at csir.co.za> Date: September 26th 2007 12:19 pm Hi, Sendmail is the oldest mta and is very powerful, but it is also complicated. I suggest you use exim, another program doing the same as sendmail, but a lot less complicated to set up. I think your problem is that you must have the mail going out set up not as coming from localhost, but from gawab.com Look at /etc/mail/sendmail.mc for changing this for sendmail. I think the line you need to edit is: dnl MASQUERADE_AS(`mydomain.com')dnl HTH, Willem On Wed, 26 Sep 2007, rkruger at gawab.com wrote: > Hi, > > Thanks for the reply.
