HI again, my other and this is very critical cause a webpage needs to send some contact mails
i created a host on my ISPconfig whit his DNS but the mail server is on another host outside my LAN so i created a MX record named mail and an alias record that points mail to the IP of the mail server.
if i do a ping to mail.optima.com.co it replies
also a telnet mail.optima.com.com 25 replies the mail server
OK it seems good but ...
but if i try to send a mail from my server the logs says:
warning: host mail.ims.com.co[22.214.171.124] greeted me with my own hostname acuario.ims.com.co
Oct 7 18:24:41 acuario postfix/smtp: warning: host mail.ims.com.co[126.96.36.199] replied to HELO/EHLO with my own hostname acuario.ims.com.co
Oct 7 18:24:41 acuario postfix/smtp: EC8732D1A4: to=<firstname.lastname@example.org>, relay=mail.ims.com.co[188.8.131.52], delay=3, status=bounced (mail for optima.com.co loops back to myself)
so i commented in the /etc/postfix/local-host-names the domain optima.com.co
and the logs now are these:
from=<email@example.com>, size=487, nrcpt=1 (queue active)
Oct 7 18:22:04 acuario postfix/local: 45EFF2D1A4: to=<firstname.lastname@example.org>, relay=local, delay=0, status=bounced (unknown user: "jorgecadavid")
i dont know what to do...... please help
