I get the following error whenever a user tries to request a password reset email:
The e-mail could not be sent.
Possible reason: your host may have disabled the mail() function.
As per recommendations I’ve read across the web, I tried several SMTP plugins. None worked. Finally, I got some debug information from one. First, the SMTP settings I used (for gmail)
server: smtp.gmail.com
port: 587
Security: TLS
Require Auth: Yes
User: <myuser>@gmail.com
Pass: mypass
Here was the result:
The result was:
bool(false)

The SMTP debugging output is shown below:
SMTP -> ERROR: Failed to connect to server: Permission denied (13)
The following From address failed: <myuser>@gmail.com : Called Mail() without being connected
This behavior is ONLY present on the remote site. The password recovery emails work just fine on the local build. Additionally, my understanding is, if this was just a webhost issue, that the SMTP plugins would have worked, which they didn’t.
Can anyone point me in the right direction here? You can see the behavior here: abundancellc.com/wp-admin – try to request password reset and type in “testuser” as the user.
Incidentally, I had no problem setting up “testuser” but I never got an email with my password – even though I requested one. What’s going on? If it’s the rackspace servers, why won’t the SMTP plugins work?
