SMTP server for incoming emails.

Is anyone aware of the existence of the SMTP server built on the IOCP basis? I tried different versions of SMTP servers (ICS, INDY), but they have low performance. In some conditions the ICS hangs and stops receiving the messages.
INDY uses one thread per connection - it takes too much memory.
The web part of the project uses mORMot and works very well.
But I also need to process incoming email messages.

Re: SMTP server for incoming emails.

Incomming SMTP is a pain - spam, viruses, hackers and etc.
For many years we have used Postfix on Linux server for that purpose.
But recently we have moved to third party service, similar to Google Apps (https://gsuite.google.com).
It's has API for dealing with mailboxes.
