Can you tell me what this options under Server > config > mail does? I cannot find them neither on ISPConfig manual nor google Reject sender and login mismatch: This reject received mail or sent mail when there is a mismatch? Adapt to temporary load spikes Mailbox soft delete by default cleaned up after 7 days. Thanks in advance.
for reject sender you have to login & send from same email, if not checked, you can log with [email protected] and send with [email protected] no idea for the 2 others…
