Bom dia pessoal, o que seria esse erro:
You can have up to 10 mechanisms in the whole chain of your
SPF record that requires DNS lookups, this means such as e.g.
exists, et al.
SPF, you tell validators to include
bulldeskmail.com.br in their decision.
By doing so, you’re also depending on both
bulldeskmail.com.br to not mess up with their
Locaweb does for example reference quite a bit, in their chain, when you follow their
include:_spf.locaweb.com.br is providing further references to e.g.
include:_spf4.locaweb.com.br, you have quite some mechanism (that requires DNS lookups) there.
And then, taking for example
include:_spf4.locaweb.com.br, that one is providing several other references:
include:spf.emailsignatures365.com include:relay.mailchannels.net a:b.spf.service-now.com a:c.spf.service-now.com a:d.spf.service-now.com
Not only Locaweb, but also Bulldesk seems to be failing with their
include:bulldeskmail.com.br, is turning you towards
a mx include:_spf.elasticemail.com
As for the
bulldeskmail.com.br does not have any
AAAA record(s) in their DNS, that one turns to a void lookup, and that
a is totally useless, in their
As for the
MX records typically reference inbound mails servers only, which it also appears Bulldesk is doing there, with pointing their
mx.inbound.elasticemail.com, it sounds to be an inbound only mail server, which makes
mx become totally useless for their
SPF record, as well.
Bulkdesk is also referencing
include:_spf.elasticemail.com, which is then referencing another
SPF (macro), with
All these things together, makes your
SPF that rely on them, become broken, as the total number of DNS lookups to fetch your
SPF (and theirs) together, goes above 10.
→ Can you fix it?
No. Fixing it would require assistance from both Locaweb and Bulldesk.
→ Can you make workarounds?
But these workarounds would be fragile, and would break without any prior notice, if Locaweb and/or Bulldesk decided to make some changes to their infrastructure.
→ What would I recommend?
I would recommend you to contact both Locaweb, and Bulldesk, and ask them respectively, whether
include:bulldeskmail.com.br are their official (and correct) way to include their mail servers to send email messages on your behalf.
It seems like the
SPF for Locaweb is the correct one, which would then mean that they have some work to do.
include:_spf4.locaweb.com.br is the worst offender, regarding this issue.
For Bulldesk, I can’t find any apparent official reference, that points towards using
include:bulldeskmail.com.br, so the contact option would probably be useful there.
That way, you can also notify them that they are doing certain things incorrectly (re:
mx above) in their current set up, which could be done by notifying them about this thread.
Although I don’t know Portuguese, I still hope that the above (even with a translator) will be useful to you, regarding explaining the underlying issue.
