ASSP Main features
Even though this help section is related to yourdomain.com, all the help sections can be applied to your other domain names or subdomains (if you have any). Where are blocked emails collected? ASSP Anti-spam has been designed and configured with great care to prevent blocking of good emails from occurring however, rarely, it can still happen. ASSP uses a "SPAM SCORING MODE" which checks each email message sent to your account and it assigns scores using several SPAM filters, sums the scores collected by each filter and then determines if the email should be considered as SPAM or NOTSPAM. All blocked emails (SPAM) are collected in a /spambox Folder where they can be inspected and managed as required.
ASSP reporting When you receive a SPAM message in your inbox you have a choice to either just delete it and move on, or better to Report it (forward as attachment) to our mail server so the anti-spam filter can learn and correct the error improving its anti-spam performance. If you find any good emails in your /spambox you can send these using "forward as attachment" to assp-notspam@yourdomain.com, which will whitelist the sending addresses preventing them from being blocked again. How to report a false positive email If you see a valid message in your /spambox IMAP or in your spambox@POP3 folder (if your server administrator activated the SPAMBOX@ plugin), you can report this email to our mail server and the anti-spam will learn and correct the error, improving its anti-spam performance. You can send these using "forward as attachment" to assp-notspam@yourdomain.com, which will whitelist the sending addresses preventing them from being blocked again. How to report a valid email (whitelisting) Every time you send an email to someone new their email address will be whitelisted automatically. For this reason, you should never reply to any spam mails as this will whitelist their addresses. You can whitelist any email address, or a complete domain, by sending an email to assp-white@yourdomain.com; you should specify one or more email addresses you want whitelisted in the email subject. If you want to whitelist a complete domain name (i.e. any_address@domain.com) you can use the wildcard *@domain.com. You can also send lists of domains and/or email addresses which should be whitelisted to assp-white@yourdomain.com;. If you become aware that email you want is being blocked simply send an email to that address or you can send an email to assp-white@yourdomain.com as described above. Could ASSP anti-spam block my local email? No, ASSP anti-spam automatically allows local senders, just be sure you are sending email correctly. The correct way to send emails is:
Too much SPAM is passing If you have too much SPAM passing (even though you are forwarding the errors to assp-spam@yourdomain.com, you can increase the sensitivity of your anti-spam setting by raising it from Normal to High, Higher or Highest. Doing so will slightly increase the possibility of stopping genuine emails. If the SPAM continues to pass even with High, Higher or Highest settings selected, please check the email headers, as it is likely the sender's address may been whitelisted at some time. In this case, please let your system administrator know so that the offending address can be checked and, if necessary, removed from the whitelist. Too many good senders are blocked If you have too many good senders blocked (even though you are forwarding the errors to assp-notspam@yourdomain.com, you can decrease the sensitivity of your anti-spam setting by lowering it from Normal to Low, Lower or Lowest. If you decrease spam sensitivity some spam could pass, however you strongly reduce the risk of blocking any good emails. If good senders are often blocked even with Low, Lower or Lowest settings and even though you are forwarding the errors to assp-notspam@yourdomain.com, please check the email headers as it is possible the sender is blacklisted, or his sending IP address may be on a blocking list. In this event please contact your system administrator who can make arrangements to allow the sender to pass. Disable anti-spam for one or more domains or email If you want to disable your ASSP anti-spam for one or more domain names (or email addresses) in your account, please contact your system administrator to arrange for your domains or email addresses to be added to the ASSP noProcessing list. Email bounces with a Service denied error If someone who is trying to contact you via email receives a bounced email with a "Service Denied error", it means their mailserver IP address is blocked by our ASSP Anti-Spam at IP address level. This may happen if that sender's IP address is on a recognized Blacklist. In this case please contact your system administrator, providing them with the full details, so that appropriate arrangements can be made to allow that sender IP address to pass. List of anti-spam ASSP email interface commands You should always receive an email confirmation message any time you send a request to the ASSP email interface (assp-spam@ ..., assp-notspam@ ..., etc). list of available ASSP anti-spam email interface commands:
The following ASSP email interface commands are available upon request to your technical support who, at their discretion, can arrange to make these available for your direct use by adding you to the allowed users list, (EmailAdmins).
How does the Delaying filter (Greylisting) work? Delaying is an additional method we provide for blocking significant amounts of spam at the mailserver level, but without resorting to heavyweight statistical analysis or other heuristical approaches. This method is also called "Greylisting". Delaying works on the principal that a correctly configured SMTP server will always attempt re-delivery of an email message if it gets a soft failure. This procedure is in standard use to ensure mail deliveries still take place even when a receiving server is offline for a while for maintenance or other reasons. How exactly does this work? When will you receive the email? Will I lose any valid email? Delaying is an additional method we provide for you to block spam at the mailserver level, it's not as efficient as the normal ASSP anti-spam "Scoring mode". This method is also called "Greylisting" and it operates on the principle that a correctly configured SMTP server will always attempt re-delivery of an email message if it gets a soft failure. Email blocked by the Delaying filter can't be collected using your spam box (or alternative ways) so we recommend only turning it ON if it's strictly required. |
