Hi.

MailScanner uses ways to interface with Postfix which are completely unsupported.

In fact, they might change any time on Postfix updates and break MailScanner (or worse: cause data loss due to MailScanner's assumptions on how postfix accesses the data). Such breakages (so far, to my knowledge, without data loss possibility) have happened in the past and might happen again in the future.

So if you insist on using MailScanner instead of the much more robust amavisd-new (or other smtp-proxying scanners), you should at least be aware that you need to be very careful whenever you update either Postfix or MailScanner.

There has been a lot of discussion about this on the postfix mailinglists in the past.
