recipient is valid. Therefor, every mail is given a time to live (TTL) which
is 24 hours in mySMTP, when a mail fails to deliver, it
will be moved to retry queue and the TTL will be adjusted
accordingly. mySMTP will check retry queue base on configured interval.
If a mail's TTL
equals or less than zero, it
will be moved to bad queue, otherwise, it will join
remote queue again for next mail deliver attempt. With
the help of queue system, mySMTP becomes one
of the most reliable mail server. You will never fail on any valid email address any more!

ISP's mail server which only allows 100 recipients in a
unlimited number of recipients in a single mail. It accepts
unlimited message size, unlimited size of file attachment.

record cache first before it queries DNS server in order
to find particular domain's mail server. The internal MX cache will
return the result immediately if the particular
domain be checked before. This will save a
lot of time wasted on waiting for DNS reply.

case this port is blocked by your ISP or network administrator; or
there is another SMTP service already running on the same
machine, you can use any other available port instead. Port 26 will
be a good choice.

DNS server is required for mail
delivery, mySMTP will detect valid DNS server automatically. However,
you still have the great flexibility to enter any
other valid DNS instead.
