Hey everyone.  An OS upgrade can indeed affect Horde if it includes an 
update to the web server or PHP or any software involved with fetching 
and reading email (ie, IMAP).

For example, I am currently holding our Debian upgrade for Apache from 
2.10 to 2.25.x until I can figure out what is causing IMP to not be able 
to authenticate with the IMAP server when using Apache 2.24.x/2.25.x. 
The issue first popped up last July 2016 with an update to 2.24.x and I 
thought it was fixed with 2.25 (and I believe I told this mailing list 
it was fixed a few weeks ago), but about an hour after I sent the "all 
clear" email to the list, I discovered the fix went away as soon as we 
restarted both Apache and php-fpm.  So I dropped back again until I can 
find time to investigate.

Later,
