My server has been updated to Hestia V1.6.1 during the night and now I’m not able to send mail from Roundcube anymore. I get the following error messages:
2022-06-29 10:57:19 H=localhost (webmail.***.com) [127.0.0.1] F=<***@***.com> rejected RCPT <***@***>: Email account is sending too many emails - rate overlimit = 1.4 / 1h
Yesterday I was sending mails in Roundcube without any problems.
The login-email-address and the from-address are the same. But $authenticated_id is empty since the error message “Email account is sending…” doesn’t contain any address.
