we have a Postfix mail relay server. Not to be an open relay we use check_sender_access restriction with allowed sender domains. Is there a way how to configure postfix to accept mails from any domain for a specified recipient? Something like

Code:

if (recipient_address==host@mydomain.com) accept; We have an admin mailbox and we need it to be accessible from everywhere.

Server :: Postfix Rejecting Mails

May 17, 2011

I've enabled popb4smtp in my mail server. Is this because of the IP 117.58.246.10 don't have a dns record? How can I sending email from this type of Ip which don't have dns entry?. But if I enable SMTP auth I can send email form this same ip. Another thing is I can connect to port 587 from the email client to send email but can't connect to port 25.

Ubuntu :: Postfix Not Forwarding E-mails Properly

Sep 9, 2010

I have Postfix set up to forward e-mails to two different addresses. This is my /etc/postfix/virtual:

Code:

I'm forwarding the message back to myself because that's the only way I know if the original message is even getting delivered in the first place.

The problem is that the e-mail isn't making it into my GMail inbox. I've checked my spam folder and it isn't there. And bafflingly, according to the logs, the message does seem to be getting sent:

Server :: Unexplained Mails In Postfix Queue / Get Rid Of Them - Why Is So?

Jul 21, 2010

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) code...

looking at the headers, there is probably something wrong with our DNS-server, which we will investigate, but I still have some questions about the failure notice:

- why are the failure notices refused? Is that a fault on the sender side, for example sending the wrong return address?

- where does this mxcorp1.pacific.net.sg[192.169.41.21] come from anyway? I don't see it anywhere in the headers.

Server :: Postfix As Receiving Mails For Multiple Domains?

Nov 15, 2010

I have configured postfix to send/receive mail from/to for two domains we manage. [URL] and [URL] Most of the cases there is no issue sending out or receiving emails. However, a few users of domainY.com complained that their senders were not able to sent them email. after much investigation, we started thinking that the mailserver failed to send us email may the failing on doing a SMTP Banner issue.

Is there anyone who knows how to deal with this SMTP banner issue with multiple domain. We want different SMTP banner when doing EHLO on different server.

Software :: Postfix -- Mails Duplicating Due To Lock Files?

Mar 3, 2010

Today I got a call from our chairman saying that he gets duplicate mails. When I checked the postfix logs, I found that it is the locks that are creating problems. The mail which duplicated was to an alias which included our chairman. In that alias, the mailbox of a user was locked since he was receiving his mails (I use dovecot for mail distribution), and hence the lock was on for that mailbox. When postfix tried to deliver the mails, it encountered the lock and the mail delivery was stopped, thus by requeuing the specific mail. While postfix retried the delivery, it found another lock with another mailbox and again the delivery was stopped, thus sending the mail back to queue

General :: Postfix And Gmail / Dropping Approx 50% Of Mails With An Error?

Nov 14, 2010

I've setup postfox on Fedora 13 in order to send emails to and from gmail. I thought this was working, but it is dropping approx 50% of mails with an error. The other 50% work OK. It seems completely random.
I've read the link but I stil dont quite understand.

My machine is just a PC, on talktalk's network in the UK.
I use dyndns to allocate a DNS alias (well several actually) to my dynamic IP address - not sure if this is relevent.

Is it failing due to a reverse DNS lookup on the dyndns host? Or is it because it cannot resolve my localhost.localdomain?

I used to have this running on opensuse and swear it used to work 100% of the time.
What am I doing wrong?

Ubuntu :: Postfix Not Sending Emails?

Jan 18, 2010

i'm not a techie but have tried my best to solve the issue without success. I have a static IP from local ISP and my computer is configured with 192.168.1.2 (LAN IP).

I have installed ubuntu server 9.04 and want to send emails from my server for which I've configured postfix. But I dont know what to do next.

My questions are:

1. Do i need to install DNS server for using postfix? If not, what should I install to send emails from this server?

2. Do I need to forward any particular port in my router?

3. If I dont have a fully qualified domain, what are the configurations I need to do to send emails?
