The "transaction" here is the normal Zope / ZODB transaction, which ensures that writes to the ZODB (and any transaction-aware RDBMS) are aborted if the request raises an exception. The "transaction-aware" feature of MaildropHost is that it holds off sending the e-mail until the transaction is committed, which ensures that you don't get a premature e-mail (in the case that the transaction is aborted), or a repeated one (if the request is retried due to ConflictError).

Well, you should know that Zope retries to execute a method up to three times in case of a ConflictError. If you send out mail using MailHost within one transaction this could cause the sending of up to three mails in case of a ConflictError. MaildropHost solves this issues. -aj
