Yes -

Late last week, at the request of others, I set up email ingest (a setup 
where people can send email to the Zulip instance).  I followed the 
directions we were pointed to; however, that seems to have broken 
outbound mail for Zulip.

The reason for this breakage is that Zulip, which requires a dedicated 
server instance to run, automatically configures all of the services on 
the server, including Postfix, and rewrites the config whenever we make 
a settings change.  This time, one of the configuration directives their 
system generated was blocking all outbound mail.  I've removed that 
directive from their Postfix instance manually to allow it to send email 
again; however, if we make further Zulip changes, their system might 
rewrite what I've done (it's already done that once) and revert these 
changes.   I've made a note of that in the server notes to try to stay 
ahead of it.

I can now send outbound email again by hand from the server, and Lars 
you should have gotten the test I sent from their system... would you 
give registration one more try for me?
