Hi,
This is the first time I am posting to this list.
Forgive me if I am making any goof ups.
I have a qmailtoaster install from
the 1.2 version ISO.
qtp-whatami v0.2.4
DISTRO=CentOS
OSVER=4.4
ARCH=i686
BUILD_DIST=cnt40
I am having the following problem
A particular domain's mail does not get delivered to the recipients
mailbox.
This is the failure message at the mail sender's end
"[EMAIL PROTECTED]
<mailto:[EMAIL PROTECTED]> on 15/09/2007 5:49 PM
Could not deliver the message in the time limit
specified. Please retry or contact your administrator.
< xxxxspam-xxxx.apacxxx.dmxxxxt.net
<http://xxxxspam-xxxx.apacxxx.dmxxxxt.net> #4.4.7 SMTP; 451 SPF lookup
failure (#4.3.0)>"
it seems your qmt trying to get sender's domain's SPF record but failed
many times and sender's server always trying to send as long as it still
below it's queuelifetime
and after that it respond back to the sender. what you can do is
- check the sender domain's SPF record from your qmt (does it get it?)
--- or ---
- disable SPF check
change /var/qmail/control/spfbehaviour into 0 or 1
