Hmm, I see.. I just checked and gmail seems to be OK with the SPF
(Received-SPF: pass ) after checking the original message.
Could it be because citadel mails using html? I mean, even with empty messages, it still appends a <body> etc on the message..
Well, it can't be solely because of that, since clearly a whole lot of email nowadays contains an HTML section, but yeah, the only thing I can think of is that something about the formatting/contents of your test messages are causing them to be considered highly likely to be spam.
I'm assuming that the core formatting of the messages is correct, and that, for example the MIME headers properly identify your HTML section as being HTML.
For test purposes, generating a plain text email (even if you do it manually) would be a useful test. You may also find that your test messages are so short that the ratio of contents to the HTML overhead is affecting the spam classification.
If you're testing with empty messages, that in and of itself might be a flag to GMail (e.g., no contents), so I'd try testing with a more realistic message.
Beyond that though, not sure what to say.
