I installed mailinabox a month ago and liked it very much. Then I needed to use the SMTP feature but it always timed out on my websites. The setup seems perfectly normal according to the docs. i.e. I tried to use emaildomain1.com as SMTP email on domain1.com so there shdouldn’t be any issue. Please help, how to figure this out? My email server is hosted on a droplet with Digital Ocean. Moreover, I tried the TLS over port 587. In addition, mostly emails from gmail take long to land in my inbox and sometimes I even don’t receive them at all. Any help will be appreciated greatly.
- Make sure your IP Address is not blacklisted: (mxtoolbox.com has a tool for this)
- MIAB uses a feature called Greylisting, so any email originating from a server your MIAB has not seen will be held for 10 minutes to help prevent spam
- Make sure you are sending to the right email address as some SMTP servers will not report a bounce back after accepting an email but rejecting the recipients.
Thank you for your input on this. I’ve set up a new server and will consider your tips there.
