strange problem wiht s_client on solaris
Hi,
this is not strictly imap-related, but i hope that it has some
relation to this list, and i have a chance to get help :-)
i'm trying to run nnimap over ssl.
i've built SSLeay-0.9.0b on solaris 2.5.1 using gcc 2.8.1
# uname -a
SunOS cache 5.6 Generic_105181-12 sun4u sparc SUNW,Ultra-4
some (small) mail messages are fetched well every time, but some
longer messages are not fetched fully: the *imap-log* buffer contains
a part of a message which was fetched, and stays "sleeping" in this
state forever. i first thought that this is a bug in nnimap, but it
appears to be a bug in s_client.
i tried to connect to the imap server manually:
video:~$ /usr/local/bin/s_client -ssl3 -connect info.vsu.ru:993

Hi,
Our squid is only used for caching and authenticating the users. He
gives any request
to his parent cache_peer (our firewall). At the moment a dns-proxy is
running on the
firewall only to serve the cache. Can I prevent the squid-cache from
sending
dns-request to the firewall ?
Thanks in advance
Martin

Here the last fetched of message #3 line contained "To: J", and i
pressed C-c to break. What could be noted is:
* without ssl (via telnet to port 143) all works fine: messages are
sent fully
* the place where the "hang" occurs is always the same (!), i.e. if i
will try to fetch other mails (which do not "hang"), and then try to
fetch the "bad" mail, the hang will ocuur at the very same line and
at the very same character.
* this is not really a "hang" because if i input some IMAP command at
that place, the server sends me the rest of the "hanged" message,
and starts to execute the new command (which may or may not hang).
e.g. if i input "10 FETCH 2 (RFC822.PEEK)", the server will send me
the rest of the message #3 and then send me the message #2.
if i input "10 FETCH 3 (RFC822.PEEK)", the server will send me the
rest of the message #3 and then send me part of the message #3, and
again hang the same line.
if i input "10 LOGOUT", the server will send me the rest of the
message #3 and then disconnect.
this looks like a buffer problem. Did anyone see something like this?
Thanks in advance for your help, and thanks a lot for your great work.
