We've just done a sucessful in situ upgrade from TW18.5 to TW18.6.
Post upgrade, Watch notification e-mails seem to have a gained a newline prefix to the message subject.
This is also evident in the TW log file where the receiving user and the subject are now on separate lines.
Taken from the source of the received e-mail...
pre upgrade Subject: wiki page "17821020_DB_1A_pp_87-88" changed by user-real-name
post upgrade Subject: =?UTF-8?Q?=0Awiki=20page=20?= =?UTF-8?Q?"18360215=5FAccounting=5Fof=5FEstate=5Fof=5FJohn=5FReaves"=20?= =?UTF-8?Q?changed=20by=20user-real-name?=
This is only affecting Watch notification emails. Email associated with notifications from the wiki's internal Message system are unaffected. That makes me think its not a generic system/sendmail subsystem issue.
Did 18.6 introduce a new configuration option I've yet to find?
I don't think I can easily demonstrate this on the "show" system since mail isn't enabled there, but I will add a couple of screen shots showing the issue in our log files.
Thanks,

Update #1 - I've done the best I'm able with the show instance. I've enabled both Watches and the internal Message system. I added a wiki page and the watch notification (log ID 7) shows the subject on a separate line to the receiving user. I created a new user and sent that user a message. Log ID 10 shows that receiving user and the message subject on the same line. Screen snip attached.
I've also attached two screen snips from our system showing the log entries for a Watch notification from just before and just after the TW18.5 to TW18.6 upgrade.
I can also confirm that Tracker notification e-mails are NOT affected by the addition of this newline prefix to the subject line since the upgrade.
The URL for the show2.tiki.org instance that demonstrates this bug is at: http://emmarrbee-11078-7423.show2.tiki.org. Note that if you get a popup asking for a username/password, please just enter "show" and "show". This is different from the initial login and password for a new Tiki which is "admin" and "admin".
For the install log, see http://emmarrbee-11078-7423.show2.tiki.org/info.txt
Note that if you see PHP errors or a Tiki claiming to be missing third party software, the instance creation is probably not finished. Please wait a couple minutes and reload.
Snapshots are database dumps of the configuration that developers can download for debugging. Once you have reproduced your bug on the show2.tiki.org instance, create a snapshot that can then be downloaded by developers for further investigation.
