		<description>Not sure if this is the right place to drop my question?  I frequently have mailerdemom return mail that I have sent, telling me I&#039;m using an incorrect email address for the addressee.  However when I Forward my initial email to the same addressee, using the same email address the email is received.

Sorry if I violated protocol here, but AOL doesn&#039;t publish a an address for online help for non-subscribers.</description>

		<description>I can confirm that was a problem on Google side and also they fixed the problem. I was suffering big time yesterday with all servers queues full with &#039;protocol compliance&#039; rejection messages. Disabling pipelining cleaned the queues. Today I tried to re-enable pipelining and delivery to Google remained ok.</description>

		<description>Thanks for those confirming comments and pointing to the source of the postfix tweaks.

Gmail may have fixed their issue because my outbound queues don&#039;t have any gmail.com messages in there.

The mailops listserv also clarified that it&#039;s pipelining support that is/was the problem and not postfix.</description>

		<description>http://archives.neohapsis.com/archives/postfix/2008-11/0166.html is the mention on the postfix list. There&#039;s no suggestion it&#039;s postfix-specific, but that list is where I saw it mentioned (and I mostly trust postfix to implement ESMTP correctly, so if a postfix box can&#039;t interoperate with gmail, I&#039;ll tend to blame gmail).

I was chatting privately with someone with the same problem on a couple of servers. Disabling pipelining seems to have resolved it, so it looks likely that Google broke pipelining support on at least some of their inbound cluster.

I&#039;ve also heard mumblings from several places that quite a few other servers are seeing the same issue, and the common factor is mailing to gmail.</description>

		<description>Hi, Frank,

My understanding is that it was mentioned on the mailop list and that post said that the issue was being tracked on the Postfix list.</description>
