[Dovecot] proxy, managesieve and ssl?

[Nicolas KOWALSKI]

Hello,

On a dovecot 2.0.14 proxy, I found that proxying managesieve works well 
when using 'starttls' option in pass_attrs, but does not work when using 
'ssl' option. The backend server is also dovecot 2.0.14; when using the 
ssl option, it reports "no auth attempts" in the logs about 
managesieve-login, and meanwhile the MUA, Thunderbird with sieve plugin, 
reports [TRYLATER] account is temporary disabled; no problem when using 
starttls option on the proxy, all works well.

I would like to use IMAPs, instead of IMAP+STARTTLS, from proxy to 
backend, and have Managesieve still working. Is this supported?

Thanks,
