Resolved MSmtp Relay to many recipients

[Heppi75]

Hi,

I have a problem with sending more than 50 mails over a second plesk server which is used as MSmtp Relay on the other plesk server.

After 50 emails the following message is generated:

Apr 17 10:45:54 merkur msmtp: host=mailserver.host tls=off auth=on user=merkur@myuser.com from=web30@myserver.com recipients=info@test.com smtpstatus=450 smtpmsg='450 4.7.1 Error: too many recipients from ipv6address' errormsg='recipient address info@test.com not accepted by the server' exitcode=EX_UNAVAILABLE

The user which is used for the relay doesn't have a restriction. Could anyone help me where I could configure this limit on the mailserver?

Maybe found it on my own - I think this postfix config should do the trick - smtpd_client_recipient_rate_limit ...
