Debugging dropped mails

[Petr Vorel]

Hi,

any idea how can I debug dropped mails in patchwork instances?
Few weeks ago I started to be unable to get patches to patchwork.ozlabs.org and
patchwork.kernel.org. Sometimes only gmail.com address is having troubles,
sometimes both my email addresses (I cc my gmail address).

Of course, I'm registered to mailing lists, I see my mail in mailing list
archives. Problems are on some kernel mailing lists, but on others as well
(buildroot, LTP).

Thanks for any tip.

Kind regards,
Petr
