Hi, I am facing an issues where LMTP delivering all mails to Junk folder, I have checked no sieve script exist either in .sieve or .svbin format but if i remove the sieve from plugin area in LMTP configuration file mails get delivered in Inbox folder.

Kindly help me to figure out this issue.

Sounds like it must be a global sieve script then. Look at your conf.d/90-sieve.conf
