Saving an email message to a file in mutt

Mutt is a text-based email client for Linux and Unix-like systems. If you want to save a particular message to a file in mutt, you can select the message then hit the v (the lowercase letter) key. In mutt, the letter is used for "view-attachments", but you can also use it to save the body of an email message to a file. If you hit the s key with the message selected or while viewing the message, you will see "<no description>" next to the number 1. If the email has any attachments they will be numbered from 2 upwards. With the first entry, i.e. the one labeled "<no description>" selected, if you hit the letter s (lowercase letter), you will see "Save to file:"

Mutt - save to file

Type the file name you wish the message to be saved under after "Save to file:" After saving the file, you can hit q several times to get back to the shell prompt. The message will be in the current directory. The file will only contain the contents of the message, not the message header, i.e., you won't see from, to, and subject lines.

Dovecot not allowing logins to check email

A user reported that she was unable to get her email today and was receiving an error in Outlook when she attempted to download her email. I logged into the email server, which runs Dovecot. I tried establishing a telnet connection to the POP3 port on the server. I was able to successfully connect to the well-known port, TCP port 110, used for POP3 connections. I could then enter the user's username with the user command, but I never received a reponse from the server, i.e. from Dovecot. I eventually had to hit ctrl-], i.e., the Ctrl and "]" keys to return to the shell prompt.

$ telnet 127.0.0.1 110
Trying 127.0.0.1...
Connected to 127.0.0.1.

Checking on whether email has gone to the spam folder and whitelisting in Gmail

If you suspect email that you wished to receive in the Inbox for your Gmail account has, instead, gone to the Spam folder, there are several ways to check the Spam folder in Gmail. If email you do want to read has gone into that folder, you can whitelist email from a particular sender or domain to ensure that future email from the sender(s) won't be routed to the Spam folder instead of the Inbox.

Adding an email address to Outlook Mail's Safe Sender list

If you use an outlook.com or hotmail.com email address and are not receiving email from someone whose email you wish to see, you may need to add the address to your safe sender's list. Otherwise, email from the sender may not even be placed in your junk email folder, but may, instead, just be discarded by Outlook Mail.

To add an email address to Outlook Mail's safe sender list, click on the gear icon at the top of the Outlook Mail window you will see after logging into your account then take the following steps:

  1. Select Options from the drop down list.
  2. Select Safe Senders.
  3. Type the email address that you wish to add as a new safe sender in the field below the pencil and trash can icons, hit Enter then click on Save.

Automated email for Let's Encrypt certificate expiration

The Let's Encrypt certificate I use for an email server again wasn't automatically renewed - see Let's Encrypt certificate expired. The Let's Encrypt certificates exipre every 90 days, so I wanted the system to automatically email me a message at least a week before the certificate expires. I manually renewed the certificate today by running the command letsencrypt renew from the root account and checked the new expiration date with the command openssl x509 -enddate -noout -i cert_pem_file_location where cert_pem_file_location is the location of the relevant cert.pem file.

# openssl x509 -enddate -noout -in /etc/letsencrypt/live/moonpoint.com/cert.pem
notAfter=Sep  8 19:14:00 2017 GMT
#

Since the new certificate expiration date is September 8, 2017, I wanted an email notice sent to me on September 1. I can then manually renew the certificate, if needed. I would then want to be notified every 3 months again indefinitely. Since the mailx utility is a standard email program found on Linux and OS X/macOS systems, I use it for sending scheduled email messages.

Using nslookup to check an email blocklist

I was notified by someone today that yesterday he had sent an email to a mailing list on an email server I maintain, but the email had not been delivered to recipients. When I checked yesterday's email log, I didn't see any email from his email address, so I asked him to resend the message. He did so, but that email message was also not delivered and I didn't see any log entry for his email address in today's email log, /var/log/maillog. He has a verzion.net email address and Verizon recently transitioned its email service to AOL. I remembered helping him make that transition last month, so I looked for any aol.com entries in the log file and found the entry below for an attempt by an AOL email server to deliver a message that was rejected at the time he told me he had sent the email today.

# grep aol /var/log/maillog
Jun  2 10:50:16 moonpoint sendmail[23955]: ruleset=check_relay, arg1=omr-a006e.m
x.aol.com, arg2=127.0.0.6, relay=omr-a006e.mx.aol.com [204.29.186.55], reject=55

Zooming in and out in an email message in Outlook 20016

If the text is too small for you to read or you want to see more text in a given area while editing an email message in the Outlook email client in Microsoft Office 2016 on an Apple laptop, such as a MacBook Pro runing the OS X/macOS operating system, you can do so without changing the font size for text in the message by holding down the control key on the keyboard while scrolling up or down with two fingers on the touchpad. If you run two fingers downwards on the touchpad while holding down the control key, you will zoom in, enlarging the text, while if you run two fingers upwards on the touchpad, you will zoom out, making the text smaller.

SORBS Blocking Email from Gmail

A family member reported that she hadn't received an email message sent to her today by a Gmail user who had sent her message in reply to the family member's email to her. Since I administer the Sendmail email server she uses, I checked the Sendmail log file at /var/log/maillog. I saw the outgoing email sent to the Gmail address, but no incoming email from that address. So I sent email messages from a Gmail account I have as well as email messages from other external addresses to the root account on the server. The other email messages arrived, but none I sent from the Gmail account arrived. So I ran tcpdump on the server to capture data to/from port 25 on the system, which is the well-known port for Simple Mail Transfer Protocol (SMTP) traffic. I then sent another email message to the root account on the Sendmail server from my Gmail account. After allowing several minutes for an attempted delivery from the Gmail server to occur, I stopped the packet capture with Ctrl-C.

# tcpdump -i enp1s4 port 25 -w smtp_2017-04-30.pcap
tcpdump: listening on enp1s4, link-type EN10MB (Ethernet), capture size 65535 bytes
^C225 packets captured
225 packets received by filter

# ls -lh smtp_2017-04-30.pcap 
-rw-r--r--. 1 tcpdump tcpdump 33K Apr 30 12:33 smtp_2017-04-30.pcap

Dovecot not responding

A user reported that she wasn't receiving any email. When I logged into the mail servers, which runs Dovecot for POP3/POP3S and used Telnet to connect to port 110, the well-known port for POP3, I didn't get any response after I entered the user command, so I exited to the telnet prompt with Ctrl-].

$ telnet 127.0.0.1 110
Trying 127.0.0.1...
Connected to 127.0.0.1.
Escape character is '^]'.
user nell
^]
telnet> quit
Connection closed.
$

I logged into the root account and checked today's and yesterday's maillog files for any references to Dovecot or POP3 issues, but saw none.

# grep -i dovecot /var/log/maillog
# grep -i dovecot /var/log/maillog.1
# grep -i pop3 /var/log/maillog.1
# grep -i pop3 /var/log/maillog

Email to Text Message

If you would like to be notified of a system event by a SMS messsage, i.e., a text message, or otherwise have a need to send information from a computer to a phone by a text message, you can use a text to email capability provided by some phone service providers. To send a text message via email to a Verizon user, you can use the Verizon phone number for the person followed by @vtext.com - don't put any dots nor dashes in the phone number, just the digits of the phone number. E.g., if the person's phone number is 555-765-4321, you would send the message to 5557654321@vtext.com. If the person uses Sprint for phone and text messaging service, you would append @messaging.sprintpcs.com to the 10-digit phone number, i.e., 5557654321@messaging.sprintpcs.com. If the user has AT&T for his/her phone service, you can text the user by appending @txt.att.net to the number, e.g. 5557654321@txt.att.net. For T-Mobile, you can append @tmomail.net to the phone number.
