Hi folks, New Ruby convert here 馃檪 I'm using the standard Net::IMAP and OpenSSL libraries to connect to an IMAP server. I can connect, examine and manipulate my INBOX, but when call the disconnect method of the imap instance it just hangs. The minimal version is almost identical to the example on page 701 of "Programming Ruby". Should I be calling some other method? require 'net/imap' require 'openssl' server, login, password = 'imap.server','my\_login','my\_password' imap = Net::IMAP::new(server, 993, true) imap.login(login,password) imap.examine('INBOX') puts "Message count: #{ imap.responses["EXISTS"]}" imap.search(["To", "Me"]).each do |message\_id| envelope = imap.fetch(message\_id, "ENVELOPE")[0].attr["ENVELOPE"] puts "#{envelope.from[0].name}: \t#{envelope.subject}" end imap.disconnect Regards, Bealach ---

I've not set up my own IMAP server to test this, but I just might. Sadly, that will not solve the problem for since I do not have admin access to the IMAP server I'm experiencing problems with (incidentally, that too is an IMAP 4 server).

I used SSL and I tried it on Gentoo Linux and Windows. The Windows is all my own compiling as I am using the Intel C++ compiler to compile everything (which of course causes me problems with some gems/addons/libraries as they are precompiled for Windows and do not include nmake makefile or VS project files and then I have to TRY to manually make a makefile for them) But I digress, on both platforms, I got the exact same lack of a problem. > **路路路** > > > On Apr 28, 2006, at 2:58 PM, Stuart Stegall wrote: > > > > > > On Apr 25, 2006, at 2:21 PM, Bealach Na Bo wrote: ---

Is your code anything like what I posted (quoting from "Programming Ruby")? I've tried that code in Debian, WinXP pro (SP2) and Win2003 all with ruby 1.8.4 and all of them hang at exactly the same place. Can you post some example code if it's different to what I posted.
