Re: Problem with LDA delivery unknown user

How did you send this email? If user is unknown (doesn't exist), Postfix will reject it directly and no chance to reach Dovecot LDA.

aha, the recipient server reported this error, not your server. It means user "jorge1@k2s.in" doesn't exist on that side.

Re: Problem with LDA delivery unknown user

Yes, I purposely sent to a wrong email.
I sent it through the postmaster account, but when the server returns the error and tries to deliver i received this error:

Jun 28 13:05:13 mail2 postfix / pipe [79621]: F1E7025F6B7: to = <postmaster@petry.net.br>, relay = dovecot, delay = 0.02, delays = 0 / 0.01 / 0 / 0.01, dsn = 5.3 .0, status = bounced (command line usage error. Command output: lda: Fatal: Invalid -f parameter: Missing domain)

- Is this "postmaster@petry..." account migrated from old server?
- Do you have issue with newly built iRedMail server (without any modification)?
- Please turn on debug mode in Dovecot and reproduce this issue again. Any detailed log in Dovecot log file (/var/log/dovecot/)?

Hi zang.

It's a New server to test and migrate after.
Do you want to connect on server and test?
I can send passwords to your email  to connect.

Re: Problem with LDA delivery unknown user

Hi.
It's a error on dovecot-2.3.1.
I update to dovecot-2.3.2 and works.

Thanks.
