Hi,

I have been having some trouble getting the freemail bofh option working for gmail.

I tried:

freemail gmail.com google.com

as described in the courier manpage, which says:

"freemail example.com domain.com" specifies that mail with a return address @example.com will be accepted only from a mail relay with a hostname in the example.com or domain.com domain.

But, when I sent a test email, I got:

Jun 28 13:48:08 vaibus courieresmtpd: error,relay=::ffff:72.14.214.196,from=<bin@gmail.com>: 517-Sender rejected: bin@gmail.com can be accepted only from Jun 28 13:48:08 vaibus courieresmtpd: error,relay=::ffff:72.14.214.196,from=<bin@gmail.com>: 517 gmail.com's mail relays.

But, 72.14.214.196 does have a google.com rDNS entry:

[root@vaibus root]# dig +short -x 72.14.214.196 hu-out-0102.google.com.

Please tell me what I am missing here.

Just a boneheaded way Google sets up their DNS.

hu-out-0102.google.com. 86400 IN A 72.14.214.192 hu-out-0102.google.com. 86400 IN A 72.14.214.193 hu-out-0102.google.com. 86400 IN A 72.14.214.194 hu-out-0102.google.com. 86400 IN A 72.14.214.195 hu-out-0102.google.com. 86400 IN A 72.14.214.196 hu-out-0102.google.com. 86400 IN A 72.14.214.197 hu-out-0102.google.com. 86400 IN A 72.14.214.198 hu-out-0102.google.com. 86400 IN A 72.14.214.199 hu-out-0102.google.com. 86400 IN A 72.14.214.200 hu-out-0102.google.com. 86400 IN A 72.14.214.201 hu-out-0102.google.com. 86400 IN A 72.14.214.202 hu-out-0102.google.com. 86400 IN A 72.14.214.203 hu-out-0102.google.com. 86400 IN A 72.14.214.204 hu-out-0102.google.com. 86400 IN A 72.14.214.205 hu-out-0102.google.com. 86400 IN A 72.14.214.206 hu-out-0102.google.com. 86400 IN A 72.14.214.207
