I set up postfix with dovecot and everything works fine (I can send e-mails both locally and from a client), except for incoming mails.
I checked my logs and whenever an email comes in, let's say that it was sent to john@example.com, postfix changes it to john@HOSTNAME.local.
I've got a private postfix relay VPS which is used by customers where they've installed their own e-mail servers in their offices and hosted over their ADSL connection. In the interests of reliable e-mail delivery, it's really not recommended to send mail directly from ISP IP addresses so I offer them the ability to use our private relay.
I've recently been investigating and playing around with linux message queues and have come across something that I don't quite understand why it happens!
If we have two programs running that are both using msgrcv() in an infinite for loop to check for messages and then send two messages, the first program running will receive the 1st message, and the second program the 2nd message?
I just install mutt and postfix on my server and I've been playing around with it.
Hi,
I wanted to know whether the POSIX message queues are statically allocated memory by the kernel based on the parameters specified in the open or as and when we send messages, memory are allocated?
Does the kernel reserve the specified memory for the message queue irrespective of whether the queue is empty or full?
I have a CentOS 5.5 64 bit mail server running Postfix. I want to do load balancing of mails sent/received to this server.
My Postfix MTA will relay mail to other two servers who will perform the SMTP service to send or receive mail messages.
Can anybody help me with this?
I'm trying to implement a mail server with postfix + policyd/amavis + mysql white/blacklist lookups.
The problem is that I would like to have "intermediate" queue between them in case one of them fails the email don't be rejected and remains in queue until the fail point recover.
My idea is the following:
postfix(25) -> queue -> mysql white/blacklist lookups (RBL) -> queue -> policyd(10031)/ama
On the postfix mailserver of our company I'm seeing several of these messages in the deferred queue (apologies for the terrible formatting, I couldn't get it any better):
I have recently replaced a Fedora Core 3 server with one running CentOS 5 for the purposes of a mail relay in a DMZ.
My problem is that when the server is sending messages to a particular remote organizaion, messages larger than 500KB don't send properly.
