Hello,

Could you please show the command and its output (you can change the IP or domain name of your target). Did you try to telnet port 587 for smtp over TLS?

EDIT: I later found this, saying: changing port to 587 got it working.

This -might- be relevant (but I'm very UNsure)
Code:
But when I let mxtoolbox check the SMTP configuration, it came back with:
SMTP Transaction Time 15.427 seconds - Not good! on Transaction Time
SendSMTPCommand: Timeout waiting for response after 15 seconds.​
...
I tried logging in with telnet port 25
Between "connected to" and "220" was almost 20 seconds.

I found out that the setting " Introduce a delay into the SMTP transaction 
  for unknown hosts and messages detected as spam. " 
in the Exim Basic editor ACL options was de culprit. 
When I disabled that option, mxtoolbox reported:
SMTP Connection Time 0.855 seconds - Good on Connection time
...
customize that value in your Exim configuration file. Here are the sections to modify:
I -wonder- if this might be some 'security' setup on the destination...[?]
