[CQ-Contest] Thoughts from a sponsor on one hour log deadlines

[David Kopacz]

Here are some additional facts to support your position, particularly

Mail Servers:

Mail servers are not always up and running. There could be emergency
maintenance being performed for a hardware failure, software failure,
backed up queue, broken connection, mis-configuration. The list is
endless. 

Some domains do not have a secondary MX (Mail Exchange) records needed
to route email to a secondary mail server when the primary mail server
is busy or down altogether. Some providers don't have secondary mail
servers.

Recipient mail servers are under no obligation to accept ANY email. Most
employ the use of DNS blacklists, RegEx filters, Tarpits and other
gadgets in order to reduce SPAM. These filtering techniques are not
perfect and often catch legitimate email. It doesn't take much to get on
some blacklists. For example, my hosting company has had servers
blacklisted for only one or two emails being delivered to a single spam
trap (email address set up only for the purpose of getting on spammers
lists)

Mail servers use queues. If a recipient email server is unavailable, the
email may be stored on the outbound mail queue for hours, sometimes
days, and even deleted after several failed delivery attempts. Each mail
server is configured according to what the administrator (operator)
chooses. A delivered email may be stuck in a recipient server queue
also.

Mail queues are often full from SPAM, slowing delivery of legitimate
mail. Outbound mail servers that permit SPAM may be blacklisted, even
temporarily, preventing the delivery of your email altogether.

Most mail servers have attachment size limits or attachment filtering.
Fortunately, our logs are typical small text files, but an aggressive
virus scanner on a mail server may block your attachment before it
leaves your server.

If the idea of placing a shorter deadline on logs submission is to speed
the scoring process, then set the deadline at a week or two, thus
providing ample time for people to return from their expeditions.

If it is to prevent cheating, the God help us all.

the current solar cycle, perhaps more. We're lucky to have any Internet
access at all.
