Dovecot sieve - How to check which username a mail is being delivered to?
Hi everyone,
I am looking for a way to check which mailbox an email is being delivered to in a global sieve filter.
After not being able to find some kind of variable that is populated by
dovecot automatically, I tried to use the Delivered-To header.
I tried a check like this:
header :is "delivered-to" "<user@domain.org>"Unfortunately, this does not only match the first occurence of the header (which can be assumed is added by dovecot), but any occurence of this header in the email, which could be added due to previous deliveries and forwards, or just cause of malice.
Is there any way to achieve this?
Best regards, Yannik

You're probably better off using envelope recipient:
envelope :is "to" "recipient@example.org"

Hi,
what happens when an email with multiple recipient is (RCPT TO) is delivered over lmtp? Will 'envelope "to"' contain multiple recipients in this case?

Hi,
According to RFC https://tools.ietf.org/html/rfc5228#section-5.4
If one of the envelope-part strings is (case insensitive) "to", then matching occurs against the TO address used in the SMTP RCPT command that resulted in this message getting delivered to this user. Note that only the most recent TO is available, and only the one relevant to this user.
So only the envelope recipient for the current delivery is available, i.e. a single address.
Regards, Tom
