Email bounces because your IP address is blacklisted
On rare occasions, you might send mail from your Gmail account, and then
receive a notice that your mail has bounced because your IP address has
been blacklisted by the recipient.
How can I fix this problem?
This is likely a temporary problem that happens only with some
recipients. One option is to simply wait until the problem goes away.
Otherwise, ask the recipient to add your domain name to their Approved
Sender's list. If their mail service doesn't support approved senders,
ask them to whitelist (approve) Gmail's sending IP addresses. After they
do either of these things, mail will no longer bounce from that recipient.
Show me Gmail IP addresses to whitelist
Ask the the recipient domain's IT administrator to add the following
Gmail IP addresses to their Simple Mail Transfer Protocol (SMTP)
gateway's whitelist:
64.18.0.0/20
64.233.160.0/19
66.102.0.0/20
66.249.80.0/20
72.14.192.0/18
74.125.0.0/16
108.177.8.0/21
172.217.0.0/19
173.194.0.0/16
207.126.144.0/20
209.85.128.0/17
216.58.192.0/19
216.239.32.0/19
2001:4860:4000::/36
2404:6800:4000::/36
2607:f8b0:4000::/36
2800:3f0:4000::/36
2a00:1450:4000::/36
2c0f:fb50:4000::/36
Why is this happening?
Some domains might use a Realtime Blacklist (RBL) service to identify
and block mail from suspected spammers. If enough of those domains'
users mark mail received from a particular IP address as spam, the RBL
can blacklist that address, blocking all mail from it. If your mail is
being bounced, it's possible that an RBL service has blacklisted your
domain's IP address.
What does Google do about this?
Google is regularly in touch with RBL services to ask that they delist
our IP addresses if they get blacklisted. However, because we can't
prevent RBL services from blacklisting any of our IP addresses, nor
guarantee the removal of them, Google support doesn't accept requests to
delist blacklisted addresses.
My domain doesn't send spam
Gmail sends mail from a number of different IP addresses that shift
regularly. If one of your messages goes out from an IP address that was
blacklisted after someone else used it to send spam, your mail can start
getting bounced. Mail bounces only from recipients who use the RBL that
blacklisted the IP address, and only while the address remains
blacklisted. Eventually, the RBL delists your IP address, or Gmail
assigns you another sending address, and your mail no longer bounces.
My domain does send spam
In that case, we ask that you stop doing so from your Gmail account.
