Hi Gang
We use Postfix and Dovecot.
To allow customers to use sub addressing we have configured postfix and dovecot with recipient_delimiter = +
This allows email addresses of the form john+doe@example.com
The way postfix processes the recipient_delimiter is by first looking up 'john+doe' and if this is not found, try again with 'john'.
This allow both to work, email accounts which contain the + sign as part of the address and sub addressing.
Collisions may happen! I am aware of this! The full email address with
- wins.
I recall dovecot also performed the same lookup in an earlier version but I might be wrong as now after some colleagues re-configured our email platform to use authentication caching and the dovecot proxy functionality, this does not work anymore.
Dovecot takes + as hard delimiter and only performs a lookup for 'john' thus returns the account 'john' does not exist.
Is there a way to configure dovecot to handle recipient_delimiter the same way postfix does by trying the full username first and only if that fails retry with the part in front of the delimiter?
Mit freundlichen Grüssen
