I'm starting to get embarrassed

So I'll probably just start using my Gmail account for submissions to Wine
anyways, but I've been having problems sending patches through Zoho.

I've followed the instructions on
https://wiki.winehq.org/Submitting_Patches
and when running 'git send-email', there are no issues on my computer. I'm
prompted for my SMTP password, git does its thing, and I've received an "OK /
250" return code every time.

Small, one-off patches seem to make it through fine, but beyond that, then the
wine-devel or the patch-list doesn't get them. Furthermore, Zoho delivers me a
message saying that wine-devel can't be reached and that they'll keep retrying
the delivery. And they do, which is where I think part of the problem might be
coming from.

---

In the first case, I tried sending a series of 7 patches. The first patch was a
very short text change, the next five were larger batch substitutions on
different strings, and the last one was a relatively short binary patch to
delete five images.

The first patch made it through pretty quickly, but the rest never showed up.
To make things more confusing, I received Zoho notices that patches 5-7
couldn't reach the list and would be retried, but nothing about 2-4. Then a few
hours later, the mailing list confirmed that patch 7 had made it through fine,
but no sign of the middle 5.

Since I had no notification from wine-devel or Zoho for patches 2-4, I tried
resending patch 2 a couple times. Everything besides patches 1 & 7 seemed to
just be falling into a black-hole though... until the next morning, every last
patch I had sent (including the repeats of patch 2) was on both wine-devel and
the patch-list, showing the original send dates, as if they had been there all
along.

---

In the second case, I had three large binary patches for deleting old images
that have since been moved onto the wiki. I tried sending them one-at-a-time,
'git send-email' gave me an OK / 250, and they never made it to the list. This
time Zoho sent me a notice saying that there was a fatal error with
wine-devel's address, specifically
"ResponseCode 421, Read timed out"

The notice said they would keep retrying the delivery for 4 days, but then I
didn't hear anything... until all of a sudden, today I see this on the patch
queue (screenshot attached). I know I didn't resend either of these patches,
much less 17 times. Weirdly enough, the wine-devel mailing list seems to
understand what's going on a little better and only shows the message once.

---

The one other pattern I have noticed is that it almost seems like the mailing
list is clocking out for business hours. The first was on a Wed evening, but it
wasn't until the next morning that everything suddenly appeared. The second
time, I tried sending in my patches before Friday evening, but there was still
no sign of them when I checked yesterday (Sun). Sure enough, they're all there
today though.

TL/DR: I know very little about how mail protocols work, and it could very well
be on my mail service's end, but it almost seems like the mailing-list is
actually receiving the emails. It then puts them in quarantine outside of
normal work-hours, which doesn't seem like a problem in isolation. Somehow the
sender is getting "delivery failed" codes though, and I only seem to get
delivery receipts sporadically, despite turning on delivery receipts in my
pipermail settings for wine-devel.
