What do for this error on sending a test email:
ERROR_EMAIL_SEND-The following From address failed: firstname.lastname@example.org
So what do I do now? Cannot do anything unless this is solved.
Opened a ticket 24 hours ago, no reply yet, so though of asking here if anyone's had this problem or have any suggestions....
I had the same issue as Dave Alston. Mandrill worked on port 25 but not 587.
Also SendGrid wouldn't connect on any port.
The SMTP block in CSF (ConfigServe Firewall) was causing the connection to not work. It has a feature called SMTP block which prevents outbound SMTP connections from all users that aren't high level (e.g. root, exim).
I had the webhost's Tech Support add the cpanel user of the domain that arpReach was installed on to the allowed list and everything works.

I'm getting the same issue.
Tried SSL, TLS and a combination of ports - to no avail.
Is there anyone who got this issue that port 25 didn't fix? Could it be some other issue - a missing PHP module or something?
For example, connecting with a POP server didn't work until I installed imap...
I was having the same problem with Mandrill.
I tried port 465 and 587 to no avail with "none" "TLS" and "SSL". However, I then tried Port 25 with TLS and it works now.
Tried everything for the three I mentioned. (don't want to use Amazon)
Have a support ticket in now
I am also getting this with SendGrid, Mailjet & Mandrill.
