Sure. Sometimes when you send a message to an address on a remote
system, the first attempt may not succeed due to a problem that it
considered temporary, either by the remote site or by the SMTP
protocol. For example, if you're sending a message to
[EMAIL PROTECTED], and your qmail can look up the address of
joesdomain.com in the DNS but it isn't able to connect to its port 25,
that's considered a temporary problem. Rather than immediately
throwing up its hands and bouncing the message back to the sender,
qmail (and other MTA's) keeps the message in its queue and tries
periodically to send it. If, after five days (by default), the message
is still undelivered, qmail bounces it as permanently undeliverable.
