When I send email from my kerio mailserver account to gmail or otherwise the recipient gets Received-SPF softfail messages. Some recipient's won't even receive my mail at all because of a softfail.

How can I configure kerio to avoid this?

The message received by recipients of my mail is as follows:

Received-SPF: softfail (google.com: domain of transitioning me<_a.t_>domain.com does not designate 1.2.3.4 as permitted sender) client-ip=1.2.3.4;
Authentication-Results: mx.google.com; spf=softfail (google.com: domain of transitioning me<_a.t_>domain.com does not designate 1.2.3.4 as permitted sender) smtp.mail=me<_a.t_>domain.com


*Note in the above I have replaced for the purposes of this post the sender's email address with me<_a.t_>domain.com and the kerio mail server's ip with 1.2.3.4

What does that mean? How do I fix this?

My domain is hosted externally - I use kerio to download email from the external mail server via POP3

Well, then make sure you are using the same server also for SMTP relaying of outgoing emails. Otherwise your IP address does not match SPF record in DNS for your domain and emails will be rejected by other servers.

Unfortunately the external host does not provide SMTP. That is why we are using the SMTP server provided with our broadband connection.

The external host provides the following email config instructions:

Outlook Settings Example:
Example of settings:

Email: info<_a.t_> yourdomain.com.au
Account name: m9093
Incoming mail: mail. yourdomain.com.au
Outgoing mail: mail.yourisp.com.au



Is there a workaround to this?

Outgoing mail: mail.yourisp.com.au



This is the SMTP adress of your email provider.

If you can send with outlook you can use this setting as relais adress for outgoing SMTP.

(Normaly SMTP is the way you are sending emails. Regardless if Outlook, Thunderbird or Kerio.)

Ask you ISP if he allows to use this adress for relaying your own email server. Some ISP have another adress for relay functions.

Travelling a lot, many of the current ISP's don't allow to use our own SMTP server ... how should we solve that problem then?

1. Use WebMail.
or
2. Have SMTP listen also on port 587 and configure the email client to use that port for sending emails. ISPs usually block only port 25.

Webmail is not an option ... laptops are made to be brought with us during travel but listening to 587 sounds like a great alternative.

Thanks,

Julien
