        Okay, you want more info.  Server is a Mac mini running 10.9 Mavericks.  This user is an iPhone on wifi (all our iPhones seem to have the problem more often than desktop Macs, but every device encounters the problem to some degree).  I figure we have no more than 30 devices checking email, 100 IMAP channels, 30 reserved for clients, 30 for non-clients, 30 from same address.  Here's another typical time-out log snippet (same user):

   
 01:33:11.818 2 IMAP-007732([108.72.228.172]) 'user@realpeople.com' connected(CRAM-MD5) [108.72.228.172]:60583->[24.73.176.117]:993(tls)(temp client)
 01:33:18.863 2 IMAP-007732([108.72.228.172]) 'user@realpeople.com' disconnected ([108.72.228.172]:60583)

 What's causing these time-outs and TLS closures???  Cheers,

   In investigating numerous complaints of IMAP connection failures, we see a lot of events like this:
   
      
 14:11:31.615 2 IMAP-007513([108.72.228.172]) 'user@realpeople.com' connected(CRAM-MD5) [108.72.228.172]:55326->[24.73.176.117]:993(tls)(temp client)
 14:11:33.477 3 IMAP-007510([108.72.228.172]) read failed. Error Code=TLS connection is being closed by peer
 14:11:33.477 2 IMAP-007510([108.72.228.172]) 'user@realpeople.com' disconnected ([108.72.228.172]:55310)   
 Eventually, after seconds to hours, the problem user does connect with no configuration changes at either end, so the problem is transient or intermittent.  Can anyone suggest what it might be, or how to make connections more consistent?  Thanks in advance for any insight.  Cheers,
