I'm aware of the capabilities of 'dpkg-reconfigure exim4-config' and the 'smarthost' option. On this machine (at home) I can deliver my own mail to its destination without having to rely on someone else. Advantages are that I get immediate feedback and the certain knowledge the mail has arrived at its destination. When out roaming, I use my own server as a smarthost to get the same advantages. > > > I want to point, that for end users is intended the 587 port, as > > > mentioned someone other too, and IMO it is not a good opinion to > > > suggest to try (check) the port 25, if the 587 is provided.

Do you really mean "criminal"? Which countries are these which criminalise looking at something which is in a public place?
