Yes. Only when the imap/pop3 process starts the post-login scripting can work.

passdb checkpassword? Or write a plugin.

is it possible to run a post-login script in a dovecot proxy with local auth?

We’re using dovecot v2.2.22, authenticating on a local database (passdb with 
sql driver), and then proxying the connections to the backend server returned 
by passdb (proxy=y and backend in “host” column). To support some legacy 
clients we should keep POP/IMAP-before-SMTP running for some time, but right 
know I don’t know how to hook up a successful authentication in the dovecot 
proxy.

I did read from http://wiki2.dovecot.org/PostLoginScripting:
“...it's not currently possible to run post-login scripts in proxies, 
because they're not actually logging in to the local Dovecot”
Does that also holds true even if the proxy is authenticating users locally 
before proxying them?

Failing that, any idea on how to get successful logins, other than parsing the 
log file?

thank you,
