Re: SMTP and Port 25

We have many applications in Delphi 6 and 7 and when sending E-Mail, we
use Indy's SMTP component. Lately we have had to unblocked port 25 on the
Exchange server in order to make the applications work.

But now, a security consultant is telling us that Port 25 needs to be
blocked again.

Recent versions of Exchange use SMTP, and port 25 is the default. If they
want to lock down the Exchange Server incoming port, why not configure your
Indy SMTP clients to use the new port number?

Can anyone give me a solution that would be relatively easy to implement
on so many applications.

Sure. Write the port number and authentication settings to mechanism that
can be shared with all the Indy SMTP clients that need it. Intranet, mapped
drive, a shared config file on the local machine, database, etc. Your
choice.

Have the apps read their configuration information from the shared resource.
