I'm trying to get blow Sieve filter to work require ["fileinto", "imap4flags", "mailbox", "body", "envelope", "vnd.dovecot.pipe", "variables", "vnd.dovecot.execute"];
if envelope :matches "To" "*@*" { set "recipient" "${0}"; set "user" "${1}"; set "recip_domain" "${2}"; }
if envelope :matches "From" "*" { set "sender" "${0}"; }
#Check if recipient is valid user if execute :output "valid_user" "user-verification" "${recipient}" { if string :matches "${valid_user}" "True" { if body :raw :contains ["message/notification"] { setflag "\\Seen"; fileinto :create "Notifications"; stop; } } }
Where user-verification is an extprogram which calls API and verify user based on email address then returns boolean (as an output to the console). Everything works fine when I will remove if string :matches "${valid_user}" "True"statement other way it looks like is not recognizing valid_uservariable. When I pipe valid_user to some script just to capture value for that variable it throws an error:
error: specified :args item `True?' is invalid.
Why question mark was added to the variable in this case? Thoughts?
