Hello,
I have a weird problem, it could be my mistake. I couldn't figure out what's going on.
If I send an email from Mozilla Thunderbird to anywhere - in this case I will send to GMail- no problem, mail goes directly to inbox. Here's the mail header:
Received-SPF: pass (google.com: domain of user@domain.co.uk designates myserverip as permitted sender) client-ip=myiphere;
Authentication-Results: mx.google.com;
spf=pass (google.com: domain of user@domain.co.uk designates myiphere as permitted sender) smtp.mail=user@domain.co.uk;
dkim=pass header.i=@domain.co.uk
Received: from [192.168.1.69] (hostipipip.range86-148.btcentralplus.com [clientip])
by mail.server.here (Postfix) with ESMTPSA id 11CD637002E7
for <myemail@gmail.com>; Thu, 9 Apr 2015 15:46:18 +0100 (BST)
DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/simple; d=domain.co.uk;
all looks good and works fine.
However, if I send an email using Roundcube my email goes to Junk folder (after adding DKIM, now it goes to inbox but still this is not the point). Here's the mail header when I send the email from Roundcube.
Received-SPF: fail (google.com: domain of user@domain.co.uk does not designate 2001:41d0:8:24ff::d7b:**** as permitted sender) client-ip=2001:41d0:8:24ff::d7b:8bb6;
Authentication-Results: mx.google.com;
spf=fail (google.com: domain of user@domain.co.uk does not designate 2001:41d0:8:24ff::d7b:**** as permitted sender) smtp.mail=user@domain.co.uk;
dkim=pass header.i=@domain.co.uk
Received: from webmail.domain.co.uk (mail.domain.co.uk [myserveriphere])

OK, the only thing I can understand for some reason SPF record becoming IPv6 and it can't resolve the record. I tried to google the problem and I've found few people had a similar issue but couldn't find a solution. I'm sure I'm missing a configuration. Can you please help me to resolve this issue?
