Hi. I have created 5 mailing lists but when I try to send in one of them I get this error in maillog

Jan 20 11:27:48 myserver postfix/smtp[17002]: 53C62F800046: to=<maillist3@mydomain.com>, relay=127.0.0.1[127.0.0.1]:10024, delay=468, delays=61/407/0/0.04, dsn=4.5.0, status=deferred (host 127.0.0.1[127.0.0.1] said: 451 4.5.0 Error in processing, id=16973-08, gen_mail_id FAILED: connect_to_sql: unable to connect to any dataset at (eval 101) line 252. (in reply to end of DATA command))

Any ideas what it means?

Re: postfix error

It might have to do with this so I'll add some of my thoughts.
The setup of the server is iRedMail with Active Directory. So this list is a distribution list created in Active Directory and it's much bigger than the other four. It has more than 2000 users.
Perhaps postfix has a limit for how many users a mail list can have?

Error in mailog:

postfix/pipe[22814]: 6CDC9F800014: to=<maillist3@mydomain.com>, relay=dovecot, delay=0.05, delays=0/0.01/0/0.04, dsn=4.3.0, status=deferred (temporary failure)

Also in queue I get (temporary failure)

Do you have correct SQL related setting (host, user, password, database name) in parameter "@storage_sql_dsn" in Amavisd config file (/etc/amavisd/amavisd.conf)?
