The users just want "Push button to make vacation go". I see... this is a little tricky, yes, and I think you're right this is the only straightforward solution at the moment. You do want to be a little careful about enabling this, though: the restriction is there in the standard to prevent automated replies from being sent for messages to mailing lists and group aliases and such, where the sender does not (and should not) know the list of final delivery addresses, and certainly doesn't want vacation replies from all of them. Since most mailing lists now set the List-* headers (which prevent vacation replies anyway), they should be OK, so this is probably only a problem if you use internal aliases which expand to lists of users. Ideally pigeonhole would take advantage of this paragraph in the standard An email address is considered to belong to the recipient if it is one of: 1. an email address known by the implementation to be associated with the recipient, and allow you to specify a dict in which to lookup a default :addresses list for each recipient. That way you could turn this parameter back off, but instead give Dovecot the information it needs to determine that a message To: was in fact directly addressed to this user.

Actually, this shouldn't have happened. Originally, it would only use 'Postmaster' when the recipient address is unknown, but that situation would never occur. With the addition of the dont_check_recipient setting, this got changed unintentionally. I assume this is done for privacy reasons, since the person the vacation response is being sent to doesn't necessarily know the user who set the vacation exists, or what their address might be. Interesting notion, but the real reason is of a more stupid nature as explained above. :) Do you think this is something people would want to configure? Since this particular feature deviates from the standard to begin with, nothing is specified about what should be done. I think the added anonymity would often be useless, because the content of the vacation message can contain all sorts of information on the recipient, including the mail address, e.g. in the signature. If you send a message with the user's email address in To:, do you get a vacation response From: the correct address? Since the recipient check is not performed, the recipient address used for the reply remained NULL and the reply code would revert to Postmaster at all times. This is fixed now. Regards, Stephan.

Normally vacation will refuse to respond to a message which doesn't have your address in one of the recipient header fields; in fact the standard says that it MUST NOT respond unless this is the case.

I assume this is done for privacy reasons, since the person the vacation response is being sent to doesn't necessarily know the user who set the vacation exists, or what their address might be. This feature is the reason I've upgraded to 2.1.7 from 1.2.15 Our users have addresses like bmor...@foo.com We also store aliases for them in LDAP like ben.mor...@foo.com. Postfix knows of these aliases and accepts mail for them. Most of our users prefer to hand out this alias as their email address Mails to bmor...@foo.com were receiving vacation auto-replies as you'd expect in 1.2.15 Mails to ben.mor...@foo.com were not due to the infamous "discarding vacation response for message implicitly delivered to bmor...@foo.com" message. I know the correct behavior is for the users to write a correct sieve script with an addresses: line, but that's not going to happen unfortunately. The users just want "Push button to make vacation go". If you send a message with the user's email address in To:, do you get a vacation response From: the correct address? No, mails to bmor...@foo.com also get Postmaster replies. With 1.2.15 we were at least getting autoreplies from bmor...@foo.com when a mail was sent to bmor...@foo.com. Ben

at my knowledge, does not work that way ,yet,
guess what you want, might work with invoking external script via sieve
wait for other responses , special stefan might give better answer about
sieve
