Hi

I'm having a customer that references ip-plus.net in his SPF policy -
but the SPF policy of that linked domain seems to be invalid since a few
days:

➜  ~ dig +short TXT ip-plus.net | grep spf
"v=spf1 ip4:193.222.75.178 ip4:212.243.7.144/29 ip4:194.209.127.144/29
ip4:212.243.190.136/29 ip4:164.128.36.0/24 ip4:164.128.36.32
ip4:195.65.89.0/24 ip4:164.128.223.0/24 ip4:217.192.233.196"
"a:mailout.ip-plus.net ip4:138.190.0.0/16 ip4:193.222.81.96/27
ip4:212.243.177.176/29 ip4:138.188.166.111 ip4:212.243.37.66 mx -all"

The policy seems to be missing a space at the point where the two
strings are concatenated - currently this is the result if validating
this policy:

SPF Permanent Error: Invalid IP4 address:
ip4:217.192.233.196a:mailout.ip-plus.net

Anyone from Swisscom / IP-Plus that could have a look at this (and add
the missing space)?

Best wishes,
Mario-------------- next part --------------
