email - SPF and DKIM help: Do the FAIL reports from DMARC indicate an issue?

I am having trouble determining if my SPF and DKIM are configured properly. Here are key details:





  • My domain is mysteryscience.com

  • We send mail from google apps, from SendGrid, and from Intercom. All seem to be working properly, although I do hear cases of our emails getting flagged as spam which is why I'm investigating this.

  • I have enabled SPF, DKIM, and DMARC

  • My SPF record seems to be semantically correct (checked here: http://www.kitterman.com/spf/validate.html)

  • My SPF TXT record is: v=spf1 ip4:198.21.0.234 include:_spf.google.com include:spf.mail.intercom.io -all

  • 198.21.0.234 is my dedicated IP address for sending through SendGrid (mail.mysteryscience.com is my CNAME forwarding to them)



I have enabled DMARC and I'm reviewing the emails I get from various mail servers. While reviewing my results from Google.com I noticed a bunch of SPF and DKIM fails. It looks like these may have been rejections of legitimate emails I sent, but I'm not sure how to read this file. Here are a few of the results, note the "fail" on a few of the < dkim > and < spf > lines. And here is a dmarcian processed version of the XML file: https://dmarcian.com/dmarc-xml/details/Ybk591jex3JpVBmW/

Can anyone help me determine if these SPF and DKIM fails are problematic?

linux - iDRAC6 Virtual Media native library cannot be loaded

When attempting to mount Virtual Media on a iDRAC6 IP KVM session I get the following error: I'm using Ubuntu 9.04 and: $ javaws -version Java(TM) Web Start 1.6.0_16 $ uname -a Linux aud22419-linux 2.6.28-15-generic #51-Ubuntu SMP Mon Aug 31 13:39:06 UTC 2009 x86_64 GNU/Linux $ firefox -version Mozilla Firefox 3.0.14, Copyright (c) 1998 - 2009 mozilla.org On Windows + IE it (unsurprisingly) works. I've just gotten off the phone with the Dell tech support and I was told it is known to work on Linux + Firefox, albeit Ubuntu is not supported (by Dell, that is). Has anyone out there managed to mount virtual media in the same scenario?

hp proliant - Smart Array P822 with HBA Mode?

We get an HP DL360 G8 with an Smart Array P822 controller. On that controller will come a HP StorageWorks D2700 . Does anybody know, that it is possible to run the Smart Array P822 in HBA mode? I found only information about the P410i, who can run HBA. If this is not supported, what you think about the LSI 9207-8e controller? Will this fit good in that setup? The Hardware we get is used but all original from HP. The StorageWorks has 25 x 900 GB SAS 10K disks. Because the disks are not new I would like to use only 22 for raid6, and the rest for spare (I need to see if the disk count is optimal or not for zfs). It would be nice if I'm not stick to SAS in future. As OS I would like to install debian stretch with zfs 0.71 as file system and software raid. I have see that hp has an page for debian to. I would like to use hba mode because it is recommend, that zfs know at most as possible about the disk, and I'm independent from the raid controller. For us zfs have many benefits, ...

linux - Awstats - outputting stats for merged Access_logs only producing stats for one server's log

I've been attempting this for two weeks and I've accessed countless number of sites on this issue and it seems there is something I'm not getting here and I'm at a lost. I manged to figure out how to merge logs from two servers together. (Taking care to only merge the matching domains together) The logs from the first server span from 15 Dec 2012 to 8 April 2014 The logs from the second server span from 2 Mar 2014 to 9 April 2014 I was able to successfully merge them using the logresolvemerge.pl script simply enermerating each log and > out_putting_it_to_file Looking at the two logs from each server the format seems exactly the same. The problem I'm having is producing the stats page for the logs. The command I've boiled it down to is /usr/share/awstats/tools/awstats_buildstaticpages.pl -configdir=/home/User/Documents/conf/ -config=example.com awstatsprog=/usr/share/awstats/wwwroot/cgi-bin/awstats.pl dir=/home/User/Documents/parced -month=all -year=all...
