Hi Rick and Floyd,
The firewall issue arose in my context because of the fact that my server is behind several firewalls. Two of these are specialised for dealing with a) inbound traffic and b) outbound traffic. When I requested that the port for IMAPS (993) be opened, I failed to specify that I needed it opened for outbound traffic. So, when the network administrator did his thing, the port was opened in the wrong direction. Once I had found the problem, I asked the network administrator to also open the GIT port 9418 in BOTH directions so I will be able to do git pulls and pushes in the future. Note however that opening GIT was just a bonus and has nothing to do with config for incoming mail. Sorry for the confusion about this, I was just super happy and felt like sharing.
Rick, when you say you're having problems with "reply-to-forum-emails" do you mean to say your connection to the IMPA server is fine? What output do you get from cron.php when your server tries to connect to the IMAP server? Is it like mine was in my first post? Or is it like the output below (from cron.php)?
Connecting to imap.gmail.com as siarn@gmail.com...
Connection established.
Searching for Unseen, Unflagged email in the folder 'INBOX'
Found 0 messages to parse. Parsing...
... used 0 dbqueries
... used 1.5728340148926 seconds
In this case, the "Connection established" is what you need to see. If you see this, there are some other settings you need to take care of to get "reply-to-forum-emails" working:
- You must set Site administration>Plugins>Message outputs>Email to 'Always send email from the No reply address'; otherwise users will see the email of the forum poster instead.
- Users receiving emails must have permissions to "reply to posts" in the forum. In My case, when I first tested it, I setup the forum in "Separate Groups" mode, and tried to have users respond to a post I made to "All Participants"... it didn't work because the users didn't have permission to post back (reply) to "All Participants".
Hope this helps!
