Tks. Just tried these two, unsuccessfully:
"\.from.*(outbound.protection.outlook.com|.google.com|.yahoo.com|mx.aol.com)\."
"\ 
from.*(outbound.protection.outlook.com|.google.com|.yahoo.com|mx.aol.com)\ 
"

However, this expression always matches:
"from.*(outbound.protection.outlook.com|.google.com|.yahoo.com|mx.aol.com)"

What am I missing?

Hello Adi,

did you try:

" from.*(outbound.protection.outlook.com|.google.com|.yahoo.com|mx.aol.com)
"

If you need to specify the posix character class:

[[:blank:]] means space and tab. With pcre it would be like [ \t]
[[:space:]] includes space, tab, newline, linefeed, formfeed, vertical tab (in
pcre like [ \t\n\r\f\v])

"[[:blank:]]from.*(outbound.protection.outlook.com|.google.com|.yahoo.com|mx.aol.com)[[:blank:]]"

Best regards,
Gerald
