Hoi zäme
One of our customers includes the SPF-Policy of ip-plus.net in his domain. Through this (and our monitoring of it), we noticed a problem that popped up this morning. If someone at ip-plus.net / Swisscom could have a look into it, that would be great.
➜ ~ 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 ip4:217.192.233.192/29 " "a:mailout.ip-plus.net ip4:138.190.0.0/16 ip4:193.222.81.96/27 ip4:212.243.177.176/29 ip4:138.188.166.0/24 ip4:138.188.176.0/24 ip4:212.243.37.66" "ip4:212.243.96.74 ip4:164.128.243.19 mx -all"
The problematic part is the missing space before the second-last "ip4:" block (after 212.243.37.66).
Error message the SPF validator throws is: SPF Permanent Error: Invalid IP4 address: ip4:212.243.37.66ip4:212.243.96.74
