This is because for whatever reason your local application chose
to submit an invalid HELO/EHLO banner when establishing the SMTP
connection to our mail infrastructure.

The culprit is the double dot ("devel.."), which should not be
there. This might have been caused by an update on your end, or
your machine having set a hostname only, rather than a complete
FQDN (and Git not coping with that properly).

If it takes longer to fix this, turning off HELO validation is an
option, though I have to admit I am not really fond of that, especially
not since it has been in place for years, and nothing has changed
on this end. :-)

Thanks, and best regards,
Peter Müller
