Hi all,
I would like some help to know why the emails sent by my VPS are not reaching GMail, even when the log looks ok to me: http://pastebin.com/6W579AYD

It worked before, sending a test email from my GMail account to an alias in my server, and now it doesn't reach my inbox even with the status=sent Ok in the log.

Any idea what I'm missing?
TIA

You sure it's not winding up in your spam folder? Do you have proper SPF records set? Do you have DKIM configured?

Not in Spam.
I followed the guide to install Postfix Gateway on Debian 6 some months ago, and it worked normally until few days ago.

I guess I haven't setup any SPF record nor DKIM, but I think that if Google can't verify the email it would be on the Spam and not just disappeared, so it should be another issue.

I just tried the mail forwarding from a Hotmail account and it reached the GMail inbox without problems. I think that Gmail discards repeated emails or something like that, and now I cannot send a test email from the same account that will receive it.

I will check what happens with the incoming emails. Thanks

Yes, if you send a message from Gmail that gets forwarded back, it won't show up in your Gmail inbox. Here is one prior post describing this behavior; if you search the forum you may find more discussion about it.

My recollection is that the solution is to use a different webmail provider for testing, or two separate Gmail accounts.
