Sending Email via SMTP
Every SMTP server's job is to send your emails. Everyone does it more or less equally. It is almost impossible to do anything new in sending a simple email message from A to B, because it is all regulated by Internet's protocols. However, not all servers make it equally easy.
We have structured our configuration in such an easy and intuitive way for our users, to allow any freedom you need. At the same time you can start sending messages directly right out of the box. It is configured with sufficient default values to install it and run it right away.
Alternative Gateway SMTP Servers
If you travel a lot with a laptop, you often end up in a location that cannot relay your emails directly. If you have specified some alternative Gateways, your message will be delivered through them. You can even let the server try to deliver the message directly first, and if it fails, try to deliver it through the gateways.
SMTP Server options
These are more advanced settings. The more sender threads you have, the quicker you will send, however if your connection speed is low and computer is not very powerful, it will not add much value and beyond certain point will even degrade performance. We recommend using the default value as this is one of the more advanced features you can change.
It is also possible to change your HELO string or let server automatically detect it. It is important to have a correct HELO string in the server, because a lot of ISP's will check that it is correct.
You can control the location of a message queue. You can put it on a network drive or a regular drive. Anywhere you want to store your temporary messages.
You can also adjust the message queue maximum size. If your temporary queue will grow bigger than this size, any additional messages will be rejected gracefully by the server. After the server becomes free, it will again start to accept new messages automatically. Thus, no messages will ever be lost or undelivered as a result of disk overflow.
