Hi,

I'm having some trouble with matching. The regexp in my dovecot.sieve file should match on email addresses, but does not.

# The code: if header :matches "From" "<[a-z0-9-]*@[a-z0-9-.]*>" { set "sender" "${1}"; } if not execute "grepfrom" ["${sender}"] { if envelope :matches "from" "*" { set "sender" "${1}"; }

This failes to match Tamara Denning <tdenning@cs.utah.edu> when I check that regexp against that string at regex101.com, it shows a match, but the log (from sieve-test) shows:

348: header test 348: starting :matches' match with i;ascii-casemap' comparator: 348: extracting From' headers from message 348: matching value Tamara Denning <tdenning@cs.utah.edu>' 348: with key `.*<[a-z0-9-]*@[a-z0-9-.]*>' => 0 348: finishing match with result: not matched

I would appreciate advice on why the match is failing, or what I can change to make it match.

Thank you!

Adam
