[courier-users] Fedora Core 3 openssl / couriertls problems

Since upgrading to Fedora Core 3, esmtpd-ssl and smtp-starttls have
stopped working for me; on a 0.47 and a 0.48.2 installation.

An SSL or STARTTLS connection can be established, and the ESMTP
greeting is sent to the client, but it appears the server is not
reading the input (from an openssl s_client session):

220 werkt.niet.net ESMTP NO UCE NO UBE You may be relaytested
EHLO TEST

[ and then... nothing ]

A strace of the couriertls process at this point shows:

select(6, [0 5], [], NULL, NULL) = 1 (in [0])
read(0, "\27\3\1\0 ", 5) = 5
read(0, "b\373\202Vqo\36\302Zg\306\rew\324\364\220f1\315\3 27G\216"...,
32) = 32
read(0, "\27\3\1\0 ", 5) = 5
read(0, "*\362\24\267|\23\224\311\331\372o\10\341\245ID\36 6z\345"...,
32) = 32
select(6, [5], [5], NULL, NULL) = 1 (out [5])
write(5, "EHLO TEST\n", 10) = 10
read(0, 0xb7e10560, 5) = -1 EAGAIN (Resource
temporarily unavailable)
select(6, [0 5], [], NULL, NULL

[ and then... nothing ]

Similar results with couriertls in 'debugging' mode:

export TLS_TRUSTCERTS=/usr/lib/courier/share/rootcerts
[vince@werkt ~]$ couriertls -port=25 -host=zeker.niet.net
-protocol=smtp
220 net.niet.net ESMTP NO UCE NO UBE You may be relay tested
STARTTLS
220 Ok
HELO TEST

[ ... ]

Both systems have
$ rpm -q openssl
openssl-0.9.7a-40

(stock Fedora Core).

How do I go about debugging this problem further?

Vince.
