Precisium has various levels of spam protection available.
You may choose the level of spam filtering you'd like for your account by emailing support@webpub.net
One of the most effective mechanisms for protecting your inbox is to use 'blacklists' of known spam-sources or virus-compromised machines.
We offer the following spam protection levels:
- None. No blacklists used.
Email must still pass an extremely basic technical 'dress code' to be received however.
- Basic. bl.spamcop.net, sbl-xbl.spamhaus.org, SPF
This provides reasonable protection with fairly low probabilities of falsely identifying genuine messages as spam.
- Standard. bl.spamcop.net, sbl-xbl.spamhaus.org, relays.ordb.org, combined.njabl.org, list.dsbl.org,SPF
You run some risk of false positivies, but usually this will be because the sender is using a system that is supporting spammers or has been compromised in some way.
Generally if you receive reports of mail to you being 'bounced' because of spam settings - the sender should first check with their own technical-support that their systems have been cleaned up.
If you have important email that is being blocked whilst on this level, but you don't wish to drop down to 'basic' protection -
you may request that we put in a special exception for certain senders.
- Aggressive. All the above blacklists and more,SPF - plus requires that the sending mailserver has a valid hostname.
This setting provides the cleanest mailbox, but runs a high risk of falsely identifying email as spam.
We suggest this only be used for mailboxes where you only wish to receive mail from systems that maintain the highest technical standards and anti-spam policies.
Note that on the 'basic' setting, you may still receive the occasional complaint from people trying to email you, that their message has bounced.
If this is because of a spamcop listing, then this situation will automatically resolve once their system has stopped being a source of spam.
Spamcop will not list a mailserver if there have been no spam reports against it within 24 hours.
It will also not list a server with only one report, and systems with only two reports will be listed for a maximum of 12 hrs after the most recently reported spam was sent.
For this reason it is a good choice for basic spam protection, and generally the occasional valid senders who mention that they are being blocked because of this, should be told to resend their message once their system administrator has cleaned up their mailserver.
