Lately it seems that some mail is being lost. I've noticed some instances when a message was sent to myself and others which I will only see if someone replies back to

Hello to all members. I am using Dovecot for 5 years, but this is my first post here. I am aware of the various autoresponder scripts for vacation autoreplies (I am using Virtual Vacation 3.1 by Mischa Peters). I have an issue with auto-replies - it is vulnerable to spamming with forged email address. Forging can be prevented with several Postfix settings, which I did in the past - but was forced

I have a mail server that handles several domains. One of these domains has decided to use Postini. For those not familiar with Postini, you set your MX records to use their mail servers. They filter mail, and deliver you only the clean virus/spam free mail. The idea is to only allow incoming mail from their mail servers so spammers are unable to send to your mail server directly. This is
