Yeah, we've encountered the same problem in our team, so having such feature would be nice! |

I am curious to understand the reason a delay is required for processing. Are either/both of you able to explain the use-case for this? |

In my case, I'm using an asynchronous system, which, when using mailpit, will receive the delivery status before it stores the sending data, which leads to conflicts. |

OK, thank you for the explanation. I will review this and hopefully get it included in the next release (at the earliest this weekend) 👍 |
