I have an email account from our own server and I can't send any emails and I'd appreciate any help with fixing it.
This is the error I'm getting:
Sender is probably forged (SPF Softfail)
Our mail server is at
My email adres is
Text (TXT) setting of domain.com is like this:
v=spf1 mx ip4:<IP of mailserver> mx:mailserver.domain.com ~all
Mailserver uses port 587
I authenticate using full firstname.lastname@example.org user when receiving and sending messages.
I'm using Outlook and we're using Exchange 2003 and GIF MailEssentials.
How can I fix this?
