I have installed postfix mail server in ubuntu machine. I am facing some
issues with the mail sending to other domain mail servers (Google, Yahoo,
Outlook...). I am using virtual domain to send the email using SMTP of the
mail server (say n...@xyz.server.com)
When I try to send multiple emails thr

Many ISPs block traffic to remote port 25. Possible solutions:

Hi,
My ISP Virginmedia (VM) suddenly made authentication compulsory a
couple of days ago. I use Thunderbird relaying through postfix. I
did have it working a few years ago on port 587 but now they want

smtp_sasl_auth_enable

Port 465 is not STARTTLS and is not directly supported by Postfix:

In this case the subject DN does not appear to be decorated with
any particularly volatile data. The server's chain is:
subject=/C=G

Looks like this may be done by calling smtp_start_tls() instead of
smtp_helo() and

Hello,
Is there a way to configure postfix to remove old mail when the mailbox size
limit is reached instead of new mail being rejected?
The basic need is limiting the amount of disk space mailbox files are using
without rejecting mail.
We have a default postfix install via RHEL 5/6 rpms (versi

Deleting mailboxes is (will not be) built into Postfix.
You can switch to maildir mode, which produces one file per messag

Hello,
Is anyone running Postfix 2.11 on an f21 machine? I'm using it and am

machine. I've got the jail Fail2ban for Postfix enabled, but the
