Re: managesieve script 'redirect' fails @ "Error: sieve: ... aborted due to temporary failure; Error: smtp-server: ... failed: SSL_accept() failed: error:1408F10B:SSL routines:ssl3_get_record:wrong version number"; direct send OK ?

For anyone interested, having dovecot sieve submit to its own submission proxy appears to be causal.

Specifically, setting

submission_host = internal.mx.example.com:60025

to submit to @ an UNencrypted port, or

submission_host = internal.mx.example.com:60465

to submit @ an ENcrypted port results in the errors I've seen.

direct submission to the dovecot submission proxy certainly works, an in the non-sieve-triggering tests above^.

also,

in brief mention here,

Sieve and SMTP submission
 https://doc.dovecot.org/configuration_manual/sieve/sieve_and_smtp_submission/

an alternative is to set sendmail_path, using the sendmail binary.

in this setup, that's postfix's sendmail; so, here, that's

sendmail_path = "/usr/sbin/sendmail.postfix"

once changed, the sieve filter redirection works.

notably, using

submission_host = internal.mx.example.com:465

, submitting to postfix's listener _also_ fails.

that _suggests_ that the problem's in dovecot's submission code, as used by sieve
