In Outlook 2007 is it possible to whitelist a domain plus all possible subdomains?

Question

I frequently receive mail from a domain which uses a newly-generated subdomain tree in the From address each time, e.g.

[e-mail]

[e-mail]

The subdomain names can't be predicted and I'm not sure whether the subdomain count is always two, but that may be the case. I want to whitelist anything coming in from example.com regardless of subdomain because Outlook generates lots of junk email false positives with these particular emails. I am forever having to rescue the messages from the Junk E-Mail folder, which is doubly annoying because after I do that Outlook just dumps the email into my inbox without applying my rules which would normally file them into a specific folder.

I have tried adding example.com to the safe senders list, but Outlook modifies this to @example.com so any subdomains are specifically excluded.

I have also tried adding @*.example.com and @*.*.example.com but these don't work either. I assume we're not allowed to use wildcards in the safe senders list?

Anyone know of any other options or a way to trick Outlook into whitelisting the entire domain?

Answer 1

Unfortunately, wildcards in the safe senders list are not supported.

If the domains follow a specific pattern and there aren't unlimited variations, you could try generating a text file of all possible domains and then importing it into the safe senders list.

Eg;

@foo1.bar1.example.com
@foo2.bar1.example.com
@foo3.bar1.example.com
@foo4.bar1.example.com
...
@foo1.bar2.example.com
@foo2.bar2.example.com
@foo3.bar2.example.com
@foo4.bar2.example.com
...

This may be more trouble than it's worth though!
