  • Sendmail relay configuration on AIX | Leave No Bit Unturned – This document describes how to set up a Sendmail e-mail gateway or relay which will be able to process incoming mail and route it to different mail servers based on domain information. The routing table is based on the Sendmail mailertable feature instead of the usual MX record based routing. This will come handy when there is a need to route mail internally in a different way than externally.

  • Disaster: LVM Performance in Snapshot Mode – MySQL Performance Blog – In many cases I speculate how things should work based on what they do and in number of cases this lead me forming too good impression about technology and when running in completely unanticipated bug or performance bottleneck. This is exactly the case with LVM
    Number of customers have reported the LVM gives very high penalty when snapshots are enabled (leave along if you try to run backup at this time) and so I decided to look into it.
  • Netexpertise » Mysql Ultra-Fast Backup with LVM – It is generally good practice to respect the two following points when backing up databases. The backup has to be:
    consistent
    fast
    Consistency is easily achieved putting a read lock on all tables beforehands. However, this isn’t always applied, and WILL definately lead to a database integrity problem at some stage.
    Once a lock has been set on the database, the backup has to be as quick as possible, all write instructions being held in the queue.

  • Five Tips for a Better sendmail Configuration – O’Reilly Media – Unix vendors bundle sendmail with the operating system and ship it out preconfigured. It is very easy to install the OS and use the sendmail configuration delivered with the system. Don't be fooled by this apparent simplicity. In the long run, it is better to take charge of your fate. Creating a custom sendmail configuration using current software and features selected for your environment will give you better performance, reliability, security, and maintainability. Here are some tips to get you started on building a better sendmail configuration.

  • mylvmbackup – mylvmbackup is a tool for quickly creating backups of a MySQL server's data files. To perform a backup, mylvmbackup obtains a read lock on all tables and flushes all server caches to disk, creates a snapshot of the volume containing the MySQL data directory, and unlocks the tables again. The snapshot process takes only a small amount of time. When it is done, the server can continue normal operations, while the actual file backup proceeds.

  • Tightening Default AIX Sendmail – disciplinux – I started looking at the default AIX configuration of sendmail for the SMTP Open Relay issues. Previously I had sent a configuration change to
    allow only specific relay-domains. However, it appears that the default sendmail configuration sets "PROMISCUOUS_RELAY" which overrides the
    RELAY-DOMAINS directive.
  • Configure sendmail to start logging Subject in maillog | www.linux4beginners.info – In this article we will learn how to configure sendmail so that you can log "Subject" in /var/log/maillog as by default sendmail does not log Subject to maillog file.

    This is really interesting. Business people many times are interested in getting mail log files analyzed. To analyse mail logs they need various field to appera in mail logs. e.g. "From", "To", "Subject" etc from the sent email. By default sendmail logs From and To fields but it does not log Subject field. In this article you will learn how to enable sendmail to log "Subject".

  • Mail server statistics – The statistics are based on completely anonymous information and were performed using randomly chosen IP addresses. When connecting to a mail server defined as an MX in the domain configuration, it can reply in a different number of ways. It may not be online, or may be refusing connections. Also, it is possible that the server does not respond back with a "220" line within the period of time we wait, nor provide a banner that identifies the type of the software running on it, at all times.
