Re: Upgrading Postfix and invalid/obseleted config values.

gt; Well, users usually interacts with IMAP/POP servers thru their mail client programs. So, it makes sense that Dovecot takes care of the quotas, instead of Postfix. Also, Wietse's suggestion of Dovecot & Postfix with LMTP is just the default I use for new or renewed installations. Fernando Maior

Re: changing relayhost based on sender

Hi Michael, Did you try to unset the default relayhost and then setup sender_dependent_relayhost_maps for the domains and users that should have a relayhost AND no setup maps for the domains and users that should not have a relayhost? Also, may be there is another way to accomplish what you want.

Re: spf configuration woes

run a process as root and cannot start it as a background service, the problem is that the user that is the owner of the service does not have enough permissions to open or access some resource (usually pid file, run file, socket file or config file). Try looking for: 1) which user/group is the owner of the service when you started it in background as a daemon. 2) see if that user/group has enough permissions to access the files it should access with read AND write permissions. Look for pid files, socket files and at last for config file. Fernando Maior

Hello, All this seems to be something very different from what postfix and other smtp usually does. So, may be the problem is with the concept, not with the implementation. May I ask you why you need to change the domain name part of the mail delivery address? Can you provide us with information

Re: LDAP canonical_maps and domain rewriting

Patrick, I do not use canonical maps at all when using LDAP. I do not need it, because I just use mailForwardingAddress (actually an alias) to map the incoming email to the real mailbox. What I do: 1. Use the qmail.schema in OpenLDAP 2. Add objectClass: qmailUser to each user account 3.

Hi, I am not an specialist in Postfix, just a common admin. Yet, I can see two things from your message: 1. You sure have a DNS resolution problem. No external server should be resolved to 192.168.x.x, that is an internal network. Also, the last two octets (255.255) are almost allways us
