Nothing to do with perl or Exim, but if you don't correct THAT behavioural mix,
it will correct YOU .. and/or one or more innocent bystanders..

Absent de-obfuscation of your 'XXXX...' not sure what THAT is doing...
NB: if this clause is where it belongs - in acl_smtp_connect you do not yet
*have* the $sender_helo_name, which is not offered to you until acl_smtp_helo.
If that is NOT throwing errors to the log, then you have the whole clause
somewhere else - too late to do you as much good as it can do.

If you have THAT, and with a 'deny' class verb, and where it belongs - in
acl_smtp_connect phase, you should hardly ever even SEE an *unwanted* 'adsl'
sourced connection survive it...
But not all ARE 'unwanted', so you should add ONE of either:
condition = ${if eq{$interface_port}{25}}
or else...
!condition = ${if eq{$interface_port}{567}}
So your broadband/dialup/WiFi/traveling users can attach and login to send from
adsl or whatever.
If that is what your 'XXXX' above was for - it ain't the best way to do that.
