Hello all, Can we skip the check of amavis with this method << 192.168.1.41 FILTER smtpd:[127.0.0.1]:10025 >> , but if you want this change to be made in GUI interface "Global Filters -> Content Filter" In amavis has banned attachments (.mp3,wav,zip..), and custom IP (directors) must be in the white-list. I want to Тhank you for your time on this query. Best regards, Nikolay
