[Dovecot] dovecot + sieve redirect failed

[Tibor Korocz]

Hi Guys,

I have a strange problem and I couldn't find any solution, I hope somebody
could help me.
I'm using postfix+dovecot+sieve combination and I tried to set up redirect.

.sieve:
require ["fileinto", "regex", "date", "relational", "vacation"];
redirect "xxxx at gmail.com";
keep;

But I get some error in the mail.log:

sieve: msgid=<1562626302.336239.1385116787283>: failed to redirect message
to <xxxxx at gmail.com> (refer to server log for more information)
Nov 22 11:39:50 server dovecot: lda(xxx at xxxx): sieve:
msgid=<1562626302.336239.1385116787283>: stored mail into mailbox 'INBOX'
Nov 22 11:39:50 server dovecot: lda(xxx at xxxx): Error: sieve: execution of
script /var/vmail/xxxx/.sieve failed, but implicit keep was successful
(user logfile /var/vmail/xxxx/.sieve.log may reveal additional details)

.sieve.log:

error: msgid=<1562626302.336239.1385116787283>: failed to redirect message
to <xxxx at gmail.com> (refer to server log for more information).

I couldn't find any other details in the logs.
Any idea what is the problem and what is the solution?

Thanks,
Tibi
