Re: Format specifiers: partial expansion + modifier

[Thomas Bohl]

Hello,

I was wondering if it is possible to use partial expansions together
with format modifiers in smtpd.conf. For example, I'd like to reduce an
email with a format like
xxxx-yyyy+z...@example.org

to

yyyy

I've tried the following variations:

%{sender.user[5:]:strip}
%{sender.user:strip[5:]}
%{%{sender.user[5:]}:strip}

I tried many more. I don't think it is possible to combine substrings 
with modifiers.
