Anti-Spam Policy

mlcastle.net and other domains hosted on this machine have some filters which attempt to block spam. If you receive a bounce message directing you to this page, then the filters have decided that your mail is spam and declined to deliver it to its intended recipient. Here are some of the possible reasons why:

address cancelled: Certain email address have been canceled because they rarely (if ever) received any non-spam mails. If you want to contact me, please use a different address.
address expired: Addresses in the temp.mlcastle.net domain are meant only to be used for a certain period of time, after which they expire. If you were given an address in this domain, it's probably because I don't want to hear from you forever.
go away, you evil spammer!: Some email addresses have been manually added to my “spammers” file because, well, they have been sending me spam. Apologies if you ended up here by accident.
go away, you evil spam domain!: Similar to the above, I also have a list of e-mail domains (the part after the @-sign) from which nothing but spam seems to eminate.
dns blocklist: I use the zen blocklist for rejecting some hosts which mostly send spam. If you are being unfairly blocked by this, see the link to get yourself off the list and/or send me a message at the email address at the bottom of the page to let me know I shouldn't be using this list anymore.
Message contains blacklisted domain: I use the SURBL system for automatically rejecting mail mentioning certain URIs known to be “spmavertized” websites. If your message was blocked, and you know that the website in question is not, in fact, advertized by spam, then please see the SURBL Lists page, match the mentioned code(s) to the appropriate list(s), and follow the procedures therein to have your site removed.
no emails directly to this address: Certain email addresses are meant to be used only for the forwarding of emails from other accounts. You shouldn't be emailing me directly at such an address; instead, email the account which forwards to this address.
Serious MIME defect detected: MIME is a standard for attaching files to messages and doing other neat things. Sometimes, a message abuses the standard so thoroughly that it's almost certainly not sent by a legitimate email program.
spam me once, shame on you; spam me twice, shame on me.: I maintain some “spam traps” which should never receive any legitimate email. Instead, the addresses appear on the web in out-of-the-way places, so that address-harvesters will see them. Then, spammers send an email to these addresses. Then, as the message implies, I never want to hear from these spammers again.
This message contains malware: An attachment is your message contains a virus or something simlar. I don't use Windows, so I couldn't be infected anyway, but I don't like these things cluttering up my inbox. Note that, under certain circumstances, a virus may forge your return address, causing you to get a bounce message even though you yourself are not infected. If this happens to you, please accept my apologies. Such situations should be relatively rare because of the way I do my filtering, but may not be completely nonexistant.
(type) files are not accepted here: Some files — notably those with extensions com, vbs, bat, pif, or scr — are almost always viruses. If you really need to send me one of these files, and it isn't a virus, put it in a ZIP file or something.

It is my belief that this set of blocking rules should result in very few non-spam messages being blocked. If, however, you think that a message you sent was not spam but it bounced anyway, then please send a note describing the problem to postmaster at mlcastle dot net and I'll see what can be done.
