For example, my return address here is=20=20 @users.sourceforge.net. However, they only resend mail to that address=20= =20 to my real address @frontier.com. I have validated to frontier.com=20=20 that I really do own the address @sourcegforge.net. So I send through=20=20 the frontier server with a From: address of sourceforge. In my case, with a KDE mailing list, when KDE gets a message, they ask=20=20 the domain of the message (sourceforge) about their policy. Recently,=20=20 they upped the level, and so told KDE to reject any mail appearing to=20=20 be from sourceforge if it didn't actually come from their. Thus I got=20=20 lots of this type of error. Someone finally convinced sourceforge that=20= =20 didn't make sense, since one of their offerings is aliased email=20=20 addresses, which were then all bouncing. So, your From: is gmail. Are you actually sending through a gmail=20=20 server, or through a yahoo server? (Note yahoo servers handle all=20=20 sorts of other domains, not lease most of the domains used by AT&T as=20=20 an ISP.)
