My customer disagrees. From their point of view mail service availabilty has a higher priority than mail archiving. > An alternative may be to use always_bcc or its brothers at the MTA level. We've used $archive_quarantine_method and a load balancer as target. A smtp-sink serves as last resort if all other servers are gone. In such a scenario mail ultimately will be lost if the sink gets into the game, but the mail service itself will remain available. p@rick -- All technical questions asked privately will be automatically answered on the list and archived for public access unless privacy is explicitely required and justified. saslfinger (debugging SMTP AUTH): <http://postfix.state-of-mind.de/patrick.koetter/saslfinger/> ------------------------------------------------------------------------------ Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.
