Extracting email address from raw events with different formats

Good Day Splunkers! I've been banging me my trying to capture all email address as recipients. Is this even possible? 

 

"status":"delivered":"recipient":"some.name@mail.com":"subject":"Thank you!":"

 

"status":"delivered":"recipient":"some.middle.name@mail.com":"subject":"Thank you!":"

 

"status":"delivered":"recipient":"\"Name Some \"<some.name@mail.com>":"subject":"Thank you!":"

 

"status":"delivered":"recipient":"some.name@mail.com,  another.name@mail.com,  more.names@mail.com subject":"Thank you!":"

 

"recipient":"\"different.name@mail.com\" <different.name@mail.com>, \"same.name@mail.com\"<same.name@mail.com>":"subject":"Thank you!":"

Hi @Will_powr,

having you so different formats, you could try using this regex

| rex "(?<mail>(\w+\.)*\w+@\w+\.\w+)"

that probably extract too many values.

Otherwise, you could use more regexes for each format:

| rex "\"(?<mail>(\w+\.)*\w+@\w+\.\w+)"
| rex "\<(?<mail>(\w+\.)*\w+@\w+\.\w+)\>"

that you can test at

Ciao.
