SPF Record Evaluation


with MEG7, we noticed a strange behaviour when the system is evaluating the SPF record of senders.

We have incoming mails being dropped with the following error:


Application=smtp, Event='Sender Policy Framework (SPF) triggered', status='Reject and close the connection', From=<[sender]@[domainname].com>, source=[host].[domainname].com([ip.address]), msgid=xxxxx, convid=xxxxx

SPF Record:

  [domainname].com           20      IN      TXT     "v=spf1 include:spf.[domainname].com ?all"


According to what we saw in the SPF RFCs, a record with "?all" should be evaluated as "neutral" and always be accepted.

Something we missunderstood?

Thanks for any info. (We turned off SPF checking for the time being.......)

Re: SPF Record Evaluation

We have the same issue in EWS 5.6 patch3.

Check this out:

There exists a KB for this issue:

I strongly suggest opening a support case with McAfee, mentioning this KB.

On the support case we have opened, we were told PAtch2 for MEG7 (out in august) would solve this problem.
