Hi there,

I have a question concerning the configuration setting

sieve_user_email

In a v2.3 setup I had it set to

sieve_user_email = %Ln@some.concrete.domain

Now I am trying to migrate to v2.4 and thought the direct translation from the old variable expansion scheme to the new scheme deployed in v2.4 would be

sieve_user_email = %{user|username|lower}@some.concrete.domain

However, this does not work. Testing the documentation yields the following error:

dovecot -n -c dovecot.conf > /dev/null

doveconf: Error: sieve: sieve settings: Failed to parse configuration: Failed to expand sieve_user_email setting variables: Unknown variable 'user' doveconf: Fatal: Error in configuration file dovecot.conf: Failed to initialize Sieve

Setting "sieve_user_email" to something without variable expansion or just commenting it out yields a configuration which is accepted by "dovecot -n".

Now I wonder:

a) v2.3 did not complain. But perhaps just because it was using "%Ln" literally?

b) In case it did work in v2.3, should it work in v2.4 also? And if so: what would be the correct syntax / variable names?

c) Under which circumstances is this setting "sieve_user_email" used? The documentation states:

https://doc.dovecot.org/main/core/summaries/settings.html#sieve_user_email

The primary e-mail address for the user.

This is used as a default when no other appropriate address is available for sending messages.

If this setting is not configured, either the postmaster or null <> address is used as a sender, depending on the action involved.

This setting is important when there is no message envelope to extract addresses from, such as when the script is executed in IMAP.

I thought that then it would make sense to use something which depends on the login-name of the IMAP-user? Or was this "sieve_user_email" intended to hold just one static email like "my_global_catch_all@some.concrete.domain"?

Kind thanks for clarification, best regards

Claus
