Hello Mailing List!
I have a complex problem with gmail. I use exim for sending mails from
different users that are connecting over smtp or with a webmailer. Gmail
rejects all mails from my domain with error messages of this type:
550-5.7.1 Our system has detected that this message is likely unsolicited
mail. To reduce the amount of spam sent to Gmail, this message has been
blocked.
I suspect, that Google does not like my Received header because the original
senders ip addresses are not in my SPF record. But I don't understand why this
could be a problem because my exim's address is in the SPF record.
My Received headers look like this:
Received: from localhost ([::1] helo=mydomain.de)
by vmd4354.contabo.host with esmtp (Exim 4.84)
(envelope-from <myuser@???>)
id 1ZBjyF-0004U1-Ni
for otheruser@???; Sun, 05 Jul 2015 15:28:35 +0200
or
Received: from x5d87bac1.dyn.telefonica.de ([93.135.186.133]
helo=desktop.localnet)
by vmd4354.contabo.host with esmtpsa
(TLS1.0:ECDHE_RSA_AES_256_CBC_SHA1:256)
(Exim 4.84)
(envelope-from <myuser@???>)
id 1ZBjyx-0004UN-77
for otheruser@???; Sun, 05 Jul 2015 15:29:19 +0200
As a solution I tried is to change the received header by exim. There is the
configuration option received_header_text . I want to change it. But exim
complains >>option "received_header_text" unknown<<.
What can I do? Has anyone an idea for me? Why am I not able to change
received_header_text ? Is it really a problem of my SPF or is Google wrong?
Google is the only provider that rejects my mails.
I hope you have ideas. The mail system seems to me more and more puzzling with
SPF, DKIM. I cannot believe that all server administratos understand what they
are doing.
