Hello,

we have a problem after updating the software with the operation of sieve scripts sending a copy of the e-mails, e-mails are not transferred.

Configuration:

dovecot-2.3.2.1 + dovecot-pigeonhole-0.5.2 + FreeBSD 11.2

log:

Sep 06 13:28:17 lda(XXX@XXX)<38615><XXX+XXX>: Info: sieve: msgid=<XXX-XXX-XXX-7788-XXX@XXXXnet>: stored mail into mailbox 'INBOX'

Sep 06 13:28:17 lda(XXX@XXX)<38615><XXX+XXX>: Info: sieve: Execution of script /usr/home/XXX/mail/XXX@XXX/.dovecot.sieve failed, but implicit keep was successful (user logfile /usr/home/XXX/mail/XXX@XXX/.dovecot.sieve.log may reveal additional details)

.dovecot.sieve.log:

error: msgid=<XXX-XXX-XXX-7788-XXX@XXXXnet>: failed to redirect message to <XXXXX@XXXXXX.com>: smtp(127.0.0.1:25): DATA failed: 552 Message header not CRLF terminated (permanent failure).

On old configuration:

dovecot 2.2 + dovecot-pigeonhole- 0.4  + FreeBSD 11.2

we don't have problem.

Has anyone had a similar problem, knows the solution?

Can you send me a pcap log (e.g. using Wireshark) from the connection between Dovecot and the MTA? Does it happen for every message?
