More on this CRAM-MD5 issue ...

Okay, I'm starting to get into the code itself, since nothing is making
any sense ...

Looking at my log for horde, I see, for the login attempt:

Feb 14 11:39:15 HORDE [error] [imp] Login Attempt(flags: 64): 131.162.6.30 to earth.hub.org:143[imap] as scrappy [on line 325 of "/usr/local/www/horde/imp/lib/IMP.php"]

Yet, if I click on 'Login to mail' to try a second time, it shows:

Feb 14 11:41:43 HORDE [error] [imp] Login Attempt(flags: 64): 131.162.6.30 to earth.hub.org:143[imap] as scrappy [on line 325 of "/usr/local/www/horde/imp/lib/IMP.php"]

Damn ... okay ... I just added 'connstr' to the logmsg output, and ...

Still searching, but why would the second attempt, where everything looks
identical, not work, if the first attempt is? :(
