Search mail from people with different addresses and incorrectly configured clients

[Sebastian Fischmeister]

Hi,

Sometimes, people's mail clients are configured incorrectly and do not
show the sender name. Often the same person uses different email
addresses. Sometimes they use different names for their alternate email
addresses.

When I search for an email originated from a specific person, I want the
search to cover all messages that match the different criteria mentioned
above.

Has anyone found a good way to use tags to aggregate emails from the
same person? Will it have some disadvantages? It sounds straightforward,
but the management of this would be quite an effort.

The alternative is to create long search strings that encompass all
email addresses of the person. This has less management effort, but I
would need to somewhere store all email addresses associated with a person.
