article #998, updated 98 days ago

A very good SPF checker:

Here is possibly the original SPF checker:

To do a deep study of a bounceback, the best tool this writer has ever seen is here:

https://testconnectivity.microsoft.com/

in the Message Analyzer tab. Just paste every header you have into there and submit, and then read. Lots and lots of excellent information comes up.

DKIM
article #1030, updated 114 days ago

DKIM is something which can be set up for a given Internet domain name and on related mail servers, which confirms validity of email, for recipient servers. It is a companion to SPF which uses SSL certificates, and it is increasingly recommended. Here are some working references.

Exchange address book, calendar, and email for Thunderbird - Bridge Exchange to IMAP
article #398, updated 525 days ago

Try DavMail:

http://davmail.sourceforge.net

It runs in the background on server, desktop, or laptop (Windows, Linux, or Mac), and it translates native Exchange protocols into that which Thunderbird and appropriate add-ins handle very well. In other words, it acts as a live bridge between Exchange protocols and Thunderbird with Lightning, for contacts and calendar. The instructions are thorough and functional.

Configuring Exchange Autodiscover
article #254, updated 1500 days ago

A Microsoft reference is here:

http://support.microsoft.com/kb/940881

with further notes here:

http://www.thirdtier.net/2009/02/setting-up-an-external-autodiscover-record-for-sbs-2008/

This has to be set at the Internet level only. We’ll use “domain.com” as the domain name, just replace it with yours.

  1. If there are any A or CNAME records pointing to “autodiscover.domain.com”, delete them. If the cert for your server uses “autodiscover.domain.com”, change it to something else, e.g., “remote.domain.com”.
  2. If there are any A or CNAME records pointing to “*.domain.com”, an asterisk for global, you’ll have to remove them too. You will need to replace with multiple specific records, or a subdomain, if you’re using a global configuration.
  3. In your Internet DNS, create a new SRV record:

At Network Solutions, the “Service” pulldown needs to have “_autodiscover”, the “Protocol” pulldown needs to have “_tcp”, “Priority” and “Weight” need to be zero, the “Port” needs to be 443, and the “Target” needs to be the A record name used in the MX record, e.g., “mail.domain.com”.

At GoDaddy, “Service” needs to contain “_autodiscover”, “Protocol” needs to contain “_tcp”, “Name” needs to contain “@”, “Priority” needs to be 0 (zero), “Weight” needs to be 0 (zero), “Port” needs to be 443, and “Target” needs to be the A record name used in the MX record, e.g., “mail.domain.com”.

You can test the setup with nslookup:

nslookup -querytype=SRV _autodiscover._tcp.domain.com

The result should be approximately thus:

Server:  dns.domain.local
Address:  99.88.77.66

Non-authoritative answer:
_autodiscover._tcp.domain.com        SRV service location:
          priority       = 0
          weight         = 0
          port           = 443
          svr hostname   = mail.domain.com
