managesieve configuration

[Gerald Galster]

Hi Dominik,

I have set ssl = required in 10-ssl.conf globally but no ssl here:

service managesieve-login {
  inet_listener sieve {
    port = 4190
  }  
  ...
}


Nevertheless, STARTTLS is offered 

"IMPLEMENTATION" "Dovecot Pigeonhole"
"SIEVE" "fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date index ihave duplicate mime foreverypart extracttext"
"NOTIFY" "mailto"
"SASL" ""
"STARTTLS"
"VERSION" "1.0"
OK "service active"


and the connection will be encrypted (tested with roudcube webmail)


> STARTTLS
< OK "Begin TLS negotiation now."

...


You can check if it works with tcpdump:

tcpdump -nn -l -A -i eth0 port 4190


Best regards
Gerald
