Tried solution posted by Thomas.Babcock, with no success, as things have obviously changed in new DokuWiki release.
Configuration, setup and testing / if any more data is needed I will post it - just ask; ->
I am using dokuwiki-2009-02-14.
Win2k3 32bit enterprise
Apache, PHP, MySQL - WAMP package
Mailserver is hMailserver 5.0
DokuWiki *can* and does send email, as I've used "notify user" on password change to check if mail works. - All right there, either with SwiftMail or butilt-in DokuWiki mailsystem.
Sometimes I do receive page changes email, usually done with other user working on wiki.
I can correctly receive page changes only if I define a catch all address in "Send change notifications to this email address"
Sometimes mails sent exercise habit of adding some users (fir subscribed, as reported by Thomas) email to from field in format:
If sending mail is set up with SwiftMail no error output is returned, and I have checked multitude of times if settings are correct (have many other services running on this mailserver and they are all OK).
If I watch in active server log, make a change on a page I am subscribed to, I can see that the DokuWiki does not try any communication with the server.
