Hi Fred Pope, I thought so but I have still a problem I put the IP ,e-mail-adr. and the user into the etc/mail/access. (restarted the sendmail) But I get the same errer I send from 194.152.103.33 to the 194.152.103.34 on ´34 I add all that stoff I guess that's correct. Maybe I rollover the error I spend to long time (2 days) with this problem. anyhow thank you Ron
