Hi, I have a postfix configuration with virtual aliases like this:
u...@example.com u...@imap.server, u...@relay.other.server There are transport maps like this: imap.server lmtp:unix:/var/imap/socket/lmtp relay.other.server smtp:[ip.address.of.other.server] With this I store incoming mails in the local IMAP server and additionally send them to another SMTP server (which is an obsolete domino server, mails have to be stored there for internal reasons there). Currently the "other server" will be down (for a long time - at least more than the default "maximal_queue_lifetime"). Because of this, I want all mails that would normally go to relay.other.server to be put ON HOLD. But I have no idea how to do this. AFAIK there is no way to define a transport rule for this, like relay.other.server HOLD relay down Adding a check_recipient_access to smtpd_recipient_restrictions also does not work (because the original recipient's address is @example.com). Any ideas? Thanks and regards! -stefan-
