Why does the SMTP configuration fail with a timeout?

Introduction:

This knowledge base article provides details about the SMTP timeout configuration.

Details:

When trying to connect an SMTP server you may receive a timeout error.

Currently, MFT has a hardcoded timeout set at 15 seconds. If the SMTP response time is higher than 15 seconds, you will see this timeout error.

Please check if there are any email relays between the MFT and SMTP server, that might increase the SMTP response times.
