I have this method defined in a program I use for checking access to  
IMAP accounts.

def tryIMAP (host, usessl, user, pass)  
retryc = false  
proto = usessl ? “IMAPS” : “IMAP”  
begin  
imap = Net::IMAP.new(host, usessl ? 993 : 143, usessl)  
rescue Net::IMAP::ByeResponseError =\> e  
imap.disconnect if imap  
STDERR.print “#{host} #{proto} #{e.to\_s}\n”;  
retryc = true  
rescue =\> e  
imap.disconnect if imap  
STDERR.print “#{host} #{proto} #{e.to\_s}\n”;  
return ‘aborted’  
end while retryc  
begin  
imap.login( user, pass)  
imap.logout  
imap.disconnect  
‘success’  
rescue Net::IMAP::NoResponseError  
‘failure’  
end  
end

As you can see I explicitly have a rescue clause for  
Net::IMAP::ByeResponseError but I still get the error raised at runtime  
☹

(Net::IMAP::ByeResponseError)948:in `receive_responses': * BYE Autologout; idle for too long from /usr/lib/ruby/1.8/net/imap.rb:932:in`synchronize’  
from /usr/lib/ruby/1.8/net/imap.rb:932:in `receive_responses' from /usr/lib/ruby/1.8/net/imap.rb:917:in`initialize’  
from /usr/lib/ruby/1.8/net/imap.rb:916:in `start' from /usr/lib/ruby/1.8/net/imap.rb:916:in`initialize’

from test.rb:94

from test.rb:93

I am testing several thousand accounts and this error happens at random  
places in the list on different runs.

Can anyone suggest where I go from here. I suspect this is a bug  
somewhere in imap.rb but I can’t reproduce this reliably. Sigh…
