SpamBlocker vs CosmoSia

■SpamBlocker supports Spam/Trash mailbox’s reassignment. Some (IMAP) mail servers support a machine learning spam filtering by using the mail data in the spam mailbox. If the spam mailbox matches between SpamBlocker and the mail server, SpamBlocker can feedback its spam filtering result to the mail server. Then the spam mail traffic can be reduced. ■SpamBlocker provides a spam filtering feature SpamBlocker(the usage is explained at the online help in the App) can filter out spams(junk mails) from the incoming mail messages by a spam filter which is generated by the SpamBlocker's built-in machine learning engine. SpamBlocker also supports 'rule based' filtering by specifying "sender's mail address" or "subject"'s substring.
 SpamBlocker supports IMAP/POP3 and can access only Inbox, spam box, trash box. SpamBlocker has no mail sending facility. As for the POP3 mail filtering, SpamBlocker has to get started before other mailers, otherwise spams will be downloaded to other mailers because POP3 has no synchronization mechanism . SpamBlocker supports HTML image blocking. SMS/MMS are not supported. SpamBlocker adapts the advertising free application model, but it has no resident toolbar, so the client area with an advertisement banner isn't narrower than other standard iOS applications.
