The pipe syntax has never worked, no idea why you think it would have.
Unfortunately at the moment, files are your best option. I do understand the

I finally tracked down the issue
It was how i was loading the certificates in the first place
that being said (and i must have missed this) 2.3.18 seems to allow
importing a cert from a program
thus sni config
local_name mail.paulkudla.net {
ssl_key =/programs/common/getssl.cert -k mail.paulkudla.net -q yes
ssl_cert =/programs/common/getssl.cert -r mail.paulkudla.net -q yes
ssl_ca =/programs/common/getssl.cert -i mail.paulkudla.net -q yes
}
would work instead of file pipes from individual text files.

You might want to get a network trace of your Thunderbird talking to the
server to see what cert actually is presented by the server, and
ideally, what domain is requested by SNI (if at all). That all happens
before the connection starts to be encrypted, so you should be able to
read it (say, with Wireshark) without having to crack any crypto ...

ok thanks for your input
I finally tracked down the issue

that being said (and i must have missed this) 2.3.18 seems to allow

#local_name mail.paulkudla.net {

either that or a pgsql select ?
