Had a delay happen on a couple of signs up to other discourse/forum places and have a suspicion on what is causing delays in my email receipt. Just wanted to get everyone’s thoughts on whether I am on right track.
What I am doing - signing up for forums.
What is happening - forum sends email confirmation of email address; I only receive the confirmation about 15 minutes later.
What I tested: same login in process with my gmail account shows forum server sends email immediately.
what I suspect happening: MiaB is rejecting initial email from forum mail server. Server retries after 15 min timeout explaing the delay.
What I could do: if really bothersome I could disable greylisting as noted in the thread below
