Search email in email viewer with condition

[Manx]

Hi

From email view I want to search for emails that DO NOT MATCH an email account or domain, for example, I want to search for all emails that do not belong to or do not contain @midominio.com .
How can I do this? What should I type in the search field?.

Is it necessary to use RegEx?

Thanks.

You will need to use Regular Expression to accomplish the query.

Possibly try

(?!.*@midominio\.com)(\w[\w\.]*@\w+\.[\w\.]+)\b

See demo here.

Thank you Richard,

I have tested the code and it works ok.

If I wanted to combine the search for several different domains, how would I do it? For example, if it DOES NOT CONTAIN @mydomain1.com NOR @mydomain2.com ?.

Thank you very much.

Maybe something like this

(?!.*@(midominio\.com|anotherdomain\.com))(\w[\w\.]*@\w+\.[\w\.]+)\b

Note that there are various regex builders online that can help.
AI LLMs (like ChatGPT) can also help build up regex.
