Too much rejects from gmail.com recipient

Hi,
A user on one of my hosted mailing lists just received a message which said he must confirm is registration, after too much rejects, before cancellation of his registration. He has a gmail mailbox (I don't know if it's matter). And maybe it is not alone :(
I have send email from my server to my personnal gmail mailbox with succes, and a test on www.mail-tester.com give my 8/10 You can see the result here : http://www.mail-tester.com/web-KUfidY
I don't have DKIM authentification on the mailman server, and I don't know if it's possible to set it up.
Else, I don't have any idea how to solve the problem :(

Are you saying this was a notice that his subscription was disabled due to bounces. Check Mailman's bounce log for information (grep the bounce logs for the users address).
If it is a warning because his subscription was disabled by bounce, check your MTA logs for possible bounce reasons.
Also, it is good to turn on the bounce processing notices, particularly bounce_notify_owner_on_disable, so that thi lis owner gets a copy of the bounce DSN that caused the disable.

It is possible. I have set up opendkim to sign list mail on at least three servers. Get opendkim from http://www.opendkim.org/ or your package manager. The README in the distribution has a section on configuring for mailing lists.
