Hello everyone,
I have a question about the outgoing rate limit for emails. I currently have a limit of 50 emails per mailbox, 200 emails per domain, and 300 emails per subscription (per hour). These limits work perfectly. Since I can't find a clear answer in the Plesk documentation and I couldn't find any precise results on Google either (and Claude and ChatGPt provide contradictory information), I would like to ask you:
What happens to messages that exceed the set limit? Are they sent automatically at a later time (i.e., placed in a queue and then sent at the next possible time slot) or are they simply rejected?
I occasionally have customers who reach the limit, but no customer has contacted me about this yet, and I wonder if they are unaware that their emails have been rejected or that our mail server has sent them in batches.
I have also attached a screenshot for visualization and am wondering how this graphic should be understood in relation to my questions.
I am also asking because I am expecting an association to send an email to all its members from time to time. This could result in 450 emails being sent in a short period of time, and I would like to have an answer ready in case the customer has problems sending them.
Apart from that, I know that this is not the right way to send so many emails
. Thank you very much for your help!
Best regards
