[sieve][regex] Matching multiple strings in the "Received" header

[Gerald Galster]

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
