Since early days of supporting SpamAssassin from amavisd it was possible to configure several per-recipient settings which shape the outcome, individually for each recipient. Examples are kill_level, which allows some recipients to be more tolerant to spam score and receive spammy mail while other recipients of the same message may be blocked. Another example is tag2_level, which marks a message in its header either as spam or not, individually. Similarly, @spam_subject_tag_maps can specify individual string to be inserted into a Subject, according to a recipient or its domain. Or the addr_extension_maps. In all cases above, SpamAssassin is called only once per message, regardless of the number of recipients. Header edits and delivery decisions are then done for each recipient individually. If header edits differ among recipients of the same message, the message is forwarded to MTA as several messages, grouped into clusters by edits needed. Now in the 2.7.0, in addition to the above, it became possible to call SpamAssassin more than once per message. See description of settings @sa_userconf_maps and @sa_username_maps in the recent RELEASE_NOTES. Recipients of a message may specify individual SA user configuration files. If this happens, SpamAssassin is called once for each cluster of same-config-file and same-username (i.e. username for Bayes checks). This does not come cheap, you pay the price of saving current SpamAssassin settings and loading a new set, and calling it for each group - so use this sparingly, only if really necessary. Unlike the per-recipient @*_maps described above, which cost almost nothing (apart from substantial programming effort).
