Infrastructure update: talktalk.net and tiscali.co.uk
URL Copied
An administrator from Open-Xchange recently posted to the Mailop list that they will be taking over mail handling for British internet provider TalkTalk, including the domains talktalk.net and tiscali.co.uk.
This means that mail from these domains will be sending from new IP addresses, and those IP addresses are:
153.92.124.143
153.92.124.183
153.92.124.184
153.92.124.205
153.92.124.224
153.92.124.240
If you run spam filtering for a mailbox provider or security service, you might want to be kind and special case these IP addresses as they begin IP warmup in the very near future.
I assume that the MX records (or what servers the MX records point to) will change as well, though I don't have any information on that and the current MX records appear unchanged, going back through all of 2024.
