I have a ubuntu server which handles mail via postfix. The server has recently been caned by spam emails and the mail logs are really large as a consequence. The logs are stored with timestamps and I was just wondering if I can just clear out the old logs without consequence to recover some disk space?
Also, being none-too-clever about such things, I am struggling to see where to change the settings for log rotation and deletion... any clues from more knowledgable folks?
Is this a question for serverfault.com ? If not, try logrotate.
According to man logrotate:
logrotate is designed to ease administration of systems that generate large
numbers of log files. It allows automatic rotation, compression, removal, and
mailing of log files. Each log file may be handled daily, weekly, monthly, or
when it grows too large.

A user of mine has 99% full disk space. They need their files for future reference but need to get rid of them somehow.
I want to export all Outlook data from 1/1/2022 and older, save it to their OneDrive, and then delete what I just exported from the exchange server.
Whats the most efficient way of doing that?
I tried archiving but I learned that makes a copy of the data and keeps it on the server.
I tried doing an export, but that appears to be almost the same as archiving but just not a "live" version.
I tried manually searching a date range, moving them to a folder, and then deleting them, but that was going to take FOREVER because of how long it took to load.
A user of mine has 99% full disk space.
In that case you can limit the size of cached data in Outlook or just consider using the non-cached mode where all the data will be retrieved from the Exchange server online. For example:
You can read more about that in the Managing Outlook Cached Mode and OST File Sizes article.

I'm working on a app which sends notifications emails. I know this is stereotypical for spam servers. I know the first question ist "How can I ensure what my server will not be listed as a spam server?" However I believe I should monitor my mailserver to ensure what every customer becomes his mails.
So the question: How can I check/monitor whether my server is listed as a spam server?
I really appreciate your help.
MXtoolbox (disclosure: I hold no relation to this site) has a great blacklist checking tool that checks all the major blacklists.
As for staying off them, make sure all your e-mails are opt-in and have an unsubscribe link within the e-mail body of every notification sent. Keep a record of all clients opting in, some hosting companies will charge you a small fortune if you get their IPs blacklisted.

Apologies if this is the wrong site - not really sure which site is best for this, but since it's SMTP-related (or is it?), I figured maybe this site had the best audience.
My company just set all of our live servers to route email through Critsend (at a cost). Apparently we've had some people complain about emails going missing, and this service lets us track it better...
I was pretty shocked, and said "There's nothing they can possibly tell us, that we can't get from the SMTP server logs!". However, I was given a huge list of features they support, including this:
Spam folder statistics with addresses
Apparently, they can tell us how many (and which!) emails went into spam folders.
I've done a little SMTP in my time, and I'm certain there is no way to get this information. So, what are they doing to claim this feature? (Note: Sadly, I don't have any access to actually see one of these reports).

Message from wepage popups in my yahoo email account. I need to x the box several times to unfreeze my computer. Then, it keeps popping up. And this occcurs before I even open any mail. exact message: "message from webp, then hi, then 40401508, then 1"
Any suggestion to get ride of it?
Run any anti-virus or anti-malware utility of your choosing on your computer. Follow any instructions that it provides on how to clean and remove whatever cruft is causing this. There are lots of free versions available online, but you should consider purchasing a subscription to a well-regarded utility from a reputable company. These days, browsing the Internet without protection is just asking for trouble!
If that doesn't work, the next step is backing up your important data, erasing your computer's disk, and re-installing your operating system from scratch. It sounds drastic, but it's really not all that bad. Plus, it will fix any other problems you've been having and probably speed up your machine noticeably.

Hey guys
Our application runs on Jboss/Apache Tomcat and the app is build on Java.
I was wondering if theres a free app out there that let us monitor our log files which are in text format whenever a Jboss exceptions shows up in the log???
At the moment we are using a tail (called BareTail) application that highlights the errors for us and someone has to keep an eye on it.
Any help appreciated thanks.
Since you're using JBoss you also want to take a look at monitoring with JBoss Operations Network (JON) or RHQ the community equivalent to JON.
Some other log monitoring tools/solutions are Chainsaw, Graylog2, Scribe, Lilith, Syslog-ng and Clarity.
Check this free opensource monitoring tool Hyperic.
Among many things it does, log monitoring is one thing.
You can install agents on the servers and configure them and this Log server will collect the information and the logs can be viewed using a webbrowser.
Other tools are Splunk, Tivoli Log Monitoring
