Hello, I'd like to be able to accept mail for only ONE domain and deliver to cyrus (configured with singleinstancestore) with lmtp and also keep /etc/aliases and unix accounts. >From what I've googled (some results from this list), I understand that I need to deliver with virtual in order to have lmtp send multiple 'rcpt to'. After reading VIRTUAL_README and ADDRESS_CLASS_README, I understood that my specific needs are not found in examples, so at first I thought of this configuration, with postfix_2.5.5-1.1_i386.deb on debian lenny x86 (note that my modification consists only of the virtual_* options, the rest is modified by debian package manager):
test:~# postconf -n: alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases append_dot_mydomain = no biff = no config_directory = /etc/postfix inet_interfaces = all mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 mydestination = mail.domain.ro, localhost myhostname = mail.domain.ro mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 myorigin = mail.domain.ro readme_directory = no recipient_delimiter = + virtual_alias_maps = $local_recipient_maps virtual_mailbox_domains = domain.ro virtual_transport = lmtp:unix:/var/run/cyrus/socket/lmtp In /etc/aliases I put (along the root aliasing defaults): test:user1,user2 then newalias'ed In linux I created user1 and user2 After testing, I discovered that it wasn't doing the alias expanding as I expected (it delivered to 'test' user, which cyrus is configured to happily accept, since it's patched to autocreate the mailbox on first delivery and I count on postfix for user validation), so I created a /etc/postfix/valiases in which I put again test: user1,user2 , postalias'ed it and removed the change in /etc/aliases, then newalias'ed. Then I adjusted "virtual_alias_maps = hash:/etc/postfix/valiases, $local_recipient_maps", /etc/init.d/postfix reload'ed and this time it worked. The next step was to remove /etc/postfix/valiases and symlink it from /etc/aliases, putting the alias back in /etc/aliases, then postalias /etc/postfix/valiases and newalias'ed. It worked as expected, again (two 'rcpt to' sent over a single session) 1. The above postconf -n with the modified 'virtual_alias_maps' does what I want. Are there other effects that I should be aware of? 2. Why it works with separate /etc/postfix/valiases file, even if it's content is the same with /etc/aliases? I have even tried to put "virtual_alias_maps = proxy:unix:passwd.byname, hash:/etc/aliases" (the same value for local_recipient_maps)... Thank you
