Summary: exim 4.69 fails to use all MX records before failing
Product: Exim
Version: 4.69
Platform: x86
OS/Version: Linux
Status: NEW
Severity: bug
Priority: high
Component: Delivery in general
AssignedTo: nigel@???
ReportedBy: david@???
CC: exim-dev@???
I'm testing exim and MX record processing.
I have two MX records - net1.coolsurf.com & net2.coolsurf.com where
net1 has an SMTP server running and net2 has none.
At least in version 4.69 it appears only net2 is tried. The MX priority
is net1 == 10 and net2 == 20.
As I understand the RFC, MX records should be tried in progressive order
and it appears here they are being tried backwards, as net1 is an async
version of qpsmtpd which will handle millions of connections and is up
during these errors.
Also, even if net1 & net2 both time out, in the case of the error below
no retry period was honored. The email was generated in a midnight cron
job (note the time stamp of 2008-07-14 00:00:17) and delivery appears to
only have been tried once, then returned as an error.
So there appear to be either 1 or 2 errors:
1) MX priority fails to be honored
2) SMTP mail delivery error is generated on first send attempt
