>invalidFormatHeloRe
No - 'validFormatHeloRe' makes this rule.
This regex was change at the begin of this year (I think) - the default is
file:files/validhelo.txt
validhelo.txt:
^(?:\w[\w\.\-]*\.\w{2,64})$
^[a-fA-F0-9]{1,4}:([a-fA-F0-9:]{1,4}){1,}(?:(?:\.\d+){3})?$

Betreff: [Assp-test] invalidFormatHeloRe
Hi,
I’m not an expert at Regexs otherwise I’d look at this myself.
I’ve had someone emailing me about problems getting mail through and at
first glance it was due to an invalid HELO. At second glance, the HELO is
actually valid and points to a domain that has a valid DNS record. The
HELO
is server.kalo.digital
This fails the default regex for invalidFormatHeloRe because the regex
stipulates that the last part of the HELO has to be between 2 and 6
characters long. This doesn’t take into account the more recent TLDs that
have been forced on the Internet of which .digital is one being 7
characters.
I can’t find anything in RFC1123 that specifically states the number of
characters for the TLD so is this a problem with the Regex rather than the
usage of TLDs with more than 6 characters?
All the best,
Colin Waring.
