I am using fetchmail in combination with procmail for mail filtering on CentOS where my mail contains various log messages.
They serve me so I could search through my mail(logs) for error strings.

You can run a periodic log analyzer of some sort to verify that you have received everything you expect to receive. Perhaps something like this.

e="[email protected]:[email protected]:[email protected]:[email protected]";

I wanted to save mail in unix in some directory, as we do in outlook (files are saved with .msg extensions). Is there any workaround for doing this.
|
you can use save command:
save [msglist] /YourDir/file
this command will append messages to file.
or you can use pine: (http://www.washington.edu/pine/tutorial.4/index.html#SavingMsg)

I'm trying to send emails programmatically with Python. The emails stay in the mail queue (mailq). Details are below.
My diagnosing abilities have reached their limit. Perhaps the issue is my ISP blocking outgoing emails from my (dynamic) IP address. Perhaps Gmail and Yahoo are expecting a different port or protocol.
... |
You can check if you have access to the mail relay by doing e.g.
nc mailrelay 25
I'd strongly suspect your ISP blocks outgoing mail traffic (there is just way too much spam on the net already, by some estimates fully 95% of all email traffic)

Unless you have a specific requirement to move your mail store; simply restore the configuration to the defaults.
That setup stores your emails in /var/spool/mail/<username> instead of your home which means any MUA you install will know where to find it without any reconfiguration.

On Debian LAMP with different PHP based CMSs I use the MTA sSMTP to send email via an email proxy (Gmail); the emails I send are only contact-form inputs transferred from any such CMS to my own email account:

ssmtp has to use your login and password to send the mail. If it would be encrypted, ssmtp would have to decrypt it, so the hacker could do the same.

dhag was on the right lines. It was squirrelmail wrapping the lines, when I exported the email it had no wrapping. Later I found a setting under options, which when I set really high took away the wrapping for my cron job logs.

The documentation lies so do not listen to it.
What you need is to uncomment the plain_server driver in conf.d/auth/30_exim4-config_examples and comment out the plain_saslauthd_server and login_saslauthd_server garbage. The saslauth driver do not work.
From there onwards, it will work as expected.

You might want to use a distribution that has a low footprint. Debian quickly comes to mind, but I can't see why you wouldn't use ubuntu or centos or even gentoo or arch.
In the end of the day, you should use the distribution you feel more comfortable with.

I need to send an email. The requirements are as follows:
Plain text and not HTML (Message type)
Plain text and not base64 (Attachments, given that my attachments are all ASCII text files.)
How do I do this?
I use Debian 10 buster generic.
|
By default, command-line mail user agents send e-mail in plaintext. And there is no need to encode in Base64 an ASCII text file (encoding is done for binary content only).
So you can simply use this command:
mailx [email protected] < mytextfile.txt

I solved the email issue by Configuring Postfix to not use ipv6. belos is way to do that.
