Mail quota exceeded - 200 limit

Hello,

The only emails we do with OVH are on one MX Plan, on a redirect basis.

On the third / forth email sent in an hour we're getting:
> Mail quota exceeded for sendmail@gxxx.xx: You have exceeded the limit of 200 messages per hour and per account. Please, re-try later.

The emails then don't get sent.

Any ideas please why we're triggering the 200 limit at such a very low number of sendmails?

i upvoted this since i have same issue

In my case the issue was the plugin used for STMP. TLS works with OVH email, but for me the server prefers SSL only and if TLS is used, after 5 emails there will be this error.

just disable antispam/antivirus in email general settings..

I used Brevo to fix the problem

Hello, did you ever find out what caused this problem?
