Bug#267895: exim4: verify = helo not checking dns addresses correctly

[Mike Fedyk]

Package: exim4
Version: 4.34-4
Severity: normal

I have this[1] log entry generated from this[2] acl.

The problem is that:

host pvnsmtp02.providian.com
pvnsmtp02.providian.com A       164.109.144.240

and

host 164.109.144.240
Name: pvnsmtp02.providian.com
Address: 164.109.144.240

They match, and the verification shouldn't fail.

[1]
host 2004-08-24 15:20:54 H=pvnsmtp02.providian.com [164.109.144.240]
Warning: Remote host 164.109.144.240 (pvnsmtp02.providian.com) incorrectly
presented itself as pvnsmtp02.providian.com
