Bug ID: 2855
Summary: $sender_host_address doesn't work well with hybrid
(v4mapped) IPv4 representation
Product: Exim
Version: N/A
Hardware: x86
OS: Linux
Status: NEW
Severity: bug
Priority: medium
Component: Mail Receipt
Assignee: unallocated@???
Reporter: hs@???
CC: exim-dev@???
I'm getting panic log entries like this:
```
2022-01-12 23:52:28 1n7mTi-00HVay-Gm failed to expand condition "${if
match_ip{$sender_host_address}{+mx}}" for always_bcc router:
"::ffff:47.38.105.140.59316" is not an IP address
2022-01-12 23:53:16 1n7mJF-00HUuL-89 failed to expand condition "${if
match_ip{$sender_host_address}{+mx}}" for always_bcc router:
"::ffff:47.48.200.86.58498.0" is not an IP address
```
- OS: IPv6 disabled
- Exim: IPv6 disabled
- Listener (according to `exiwhat` and `ss -lt`) listens on IPv4 only
In host.c host_ntoa() probably calls inet_ntop() which returns the v4mapped
form.
I'm not sure yet and need to dig more into this.
It happens since a recent upgrade from Debian 10 to Debian 11 (and thus from
Exim 4.92 (?) to Exim 4.94.2)
