-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Over the past weekend, I added SPF screening on the MTA at shorewall.net. SPF is a mechanism for a domain to use DNS to publish a list of those IP addresses that are used to send legitimate email from that domain. A receiving MTA can use that published information to determine if email from a domain is being sent through an MTA belo...

I am inquiring about how to setup a proper SPF record. I know there are SPF wizards/generators available but each seem to have a different "opinion" of what should be included and what should not be included. Let me give you a scenario of my setup, and hopefully someone can help me out. My domain is: test.com My mailserver hostna...

Say someone has setup spf for his domain and sends an email to a user that has in roundcube enabled the sieve forward. If the message is forwarded without altering the message headers, this could result in a message being blocked or not relayed, because sending hosts ip, is not in the spf of the from: domain. Possible...

Hello Dovecot gurus, I've set up SPF checking on my postfix gateway and have confirmed that messages from domains set with hard fails that don't come from a good sender are rejected outright. Messages from domains set with a softfail that come from bad sources are tagged in the message header with "Softfail (domain owner dis...

Since I've upgraded to dovecot 2.0.13 + Pigeonhole 0.2.3 (Gentoo package) I've received a few complains of users about rejected messages. Investigating the problem, I've seen that when the external sender server publishes SPF information, when some message is sent from there to one of my users that has a Sieve redirect action active to another external system (that does SPF validation), the message is rejected because our system only changes the envelope "rcpt to" in the redirection and the "mail from...

...t the ''Return-Path'' of an email when using ActionMailer. Without the ability to set the ''Return-Path'' of an email, it is impossible to avoid being labeled as ''spam'' by many SMTP gateways if trying to send mail on another''s behalf. SPF doesn''t care about the ''from'' line in an email, only the ''Return-Path''. Why would I want to do that? Because I am working as a consultant for another company, and when responding to bug reports I want to make things easier for the users by replying...

There's no ambiguity here, if you send a message, you are the sender. The envelope from should be yours.
