[exim] exim acl check helo conf

Hi



Hello

first of all ask you to excuse my language, because I'm Latin and I helped
translators

I could explain that makes this acl:

acl_check_helo:



# Include Vexim specific helo ACLs

.include /etc/exim/vexim-acl-check-helo.conf



and also makes the file vexim-acl-check-helo.conf



I recently had a problem telling me that many connections were made at
sevidor smtp and users could not send emails, I found this in the log exim

2016-05-26 05:11:14 H=(ip-static-173-243-124-205.as5577.net)
[173.243.124.205] rejected EHLO or HELO
ip-static--173-243-124-205.as5577.net: "Dropped spammer pretending to be us"



a line like this, then my question is whether I should block those ips in
the file or directly ip_tables ¿?



Thanks for your help
