[courier-users] Mail loop with 2 backup servers

[Daniel Heule]

Hello, i have problems. I have a domain with 1 master with 2 Backup mailhosts. The MX loocks like this: ;; ANSWER SECTION: redplace.ch. 1D IN MX 20 mailhost.blackcrypt.ch. redplace.ch. 1D IN MX 30 mailhost.glag.ch. redplace.ch. 1D IN MX 10 mailhost.redplace.ch. I have only set esmtpacceptmailfor on the backup servers. On the beginning it's shining work. But on a long downtime of the master server, the mail is correct devlivered to mailhost.blackcrypt.ch. this mailserver delivers to redplace.ch this to blackcrypt.ch and so on. this end's up in a loop detect. All tree mail server are courier. Can someone help me ? what must i do ?
