Perhaps I misunderstand the point, but this is about DBSL, not spamcop or sorbs.
According to dbsl.org:
The DSBL lists contain the IP addresses of servers which have relayed special test messages to [email address]; this can happen if the server is an open relay, an open proxy or has another vulnerability that allows anybody to deliver email to anywhere, through that server.
Effectively their listing of a gmail server implies that the server has been either hacked or just open to un-authenticated relaying. So is DBSL right or wrong here?

Some organizations, like SpamCop and Sorbs, keep track of email spam so email providers/ISPs can use it to prevent spam from being delivered to their users. Occasionally, Gmail is listed on SpamCop because we do not reveal the IP address of our users. We don't reveal IP addresses as part of our ongoing effort to protect every user's privacy. Unfortunately, this can cause delivery problems for Gmail messages because some email providers/ISPs reject all messages sent from services listed on SpamCop and Sorbs. Neither SpamCop nor Sorbs intend for their lists to block all Gmail messages. In fact, both organizations recommend that their lists are not used as 'stand-alone signals' in blocking spam, but unfortunately, this recommendation is sometimes ignored. As a result, some messages sent from Gmail might be delayed, or even bounced back (in which case you would receive a failed delivery notification).
We take every measure to make sure that all valid messages are delivered, and we're working hard to keep delivery problems to a minimum. While we continue to address this problem, we ask that Gmail users experiencing delivery delays or Gmail users whose messages are bouncing back to their accounts, to please inform the recipient's mail provider about the issue.
If you are an email administrator, learn more about what you can do to make sure Gmail messages are delivered to your users.

I have experienced an intermittent problem with (Gmail) e-mails bouncing back. I get the following error message:
"PERM_FAILURE: SMTP Error (state 12): 553 sorry, your mailserver [18.104.22.168] is rejected by Seehttp://dsbl.org/main"
There is some variation in the above mail delivery notification based on the mail server IP e.g. 22.214.171.124; 126.96.36.199.
It appears that these mail server addresses (?) have been blacklisted by dsbl.org (Distributed Sender Blackhole List). I have reported the situation to my service provider and the intended recipients' service provider/s and the prognosis is that these servers are used by Gmail and thus it is a "Gmail problem". Now this may be the usual "shoulder slope" and I would appreciate comment from someone who knows more about it than I do.
This problem does not seem to occur with my other e-mail account (telkomsa.net) when using MS Outlook as my e-mail client.
