mail.zsh.org: planned downtime: Tuesday, 12:30 UTC

[Daniel Shahaf <d.s@xxxxxxxxxxxxxxxxxx>]

All email services on zsh.org will be down for maintenance tomorrow
(Tuesday), as an embargo is lifted on exploitable vulnerabilities in our
MTA (https://lists.exim.org/lurker/message/20210421.123632.08bb711a.en.html).

During the downtime, email to *@zsh.org will not flow; it will be
queued on the originating MTAs, as usual in SMTP.
 
The downtime will start at 12:30 UTC and end as soon as one of the
volunteer sysadmins has reviewed the exploitable vulnerabilities and,
if necessary, deployed the requisite patches.
