Great idea to test that. I began with it (before going to edebug more
functions):

Did twice the same request. Did take twice 5 mins...

In my case, the culprit seems well to be our mail server, then.

I answered this in the early beginning of the thread: time taken for opening
the link seems to be (linearly?) dependant on the size of the mail groups.

In INBOX.mc (the group for all work-related emails, containing ~27,000
emails), it takes ~5 mins to open a link from Org.

In other normally-sized groups (a couple of 100's of emails), it took a couple
of seconds (> 10 s).

Maybe a problem is that I keep all of my emails (but the spams...) since the
beginning: now, over 140,000 emails entered my INBOX -- only the spams left
it.

What would be your pieces of advice in such a case? Do I need to test
something extra? Get a local imap server? Others (like asking for fixing the
search on our Courier mail server)?

Best regards,
  Seb
