If you ever receive a mail with an attachment named “winmail.dat” then may be disappointed. It is a special format used by Microsoft Exchange, it contains the files attached to the mail and need some software to extract them.

Hopefully, there is a little and effecient utility named “tnef” to extract the files.

Install it: pkg_add tnef

List files: tnef -t winmail.dat

Extract files: tnef winmail.dat

That’s all !

How to send html signature in mu4e

I switched to mu4e to manage my mails at work, and also to send mails. But in our corporation we all have a signature that include our logo and some hypertext links, so I couldn’t just insert my signature and be done with that. There is a simple way to deal with this problem, I fetched the html part of my signature (which include an image in base64) and pasted it into my emacs config file this way.

(setq mu4e-compose-signature 
  "<#part type=text/html><html><body><p>Hello ! I am the html signature which can contains anything in html !</p></body></html><#/part>" )

I pasted my signature instead of the hello world text of course, but you only have to use the part tag and you are done ! The rest of your mails will be plain text, except this part.

Mbsync and imap login problem

I have not found any answer about this so I share my fixed. I wanted to use mbsync with one IMAP server and encountered the following error.

IMAP command 'AUTHENTICATE DIGEST-MD5' returned an error: NO Authentication failed

A fix is to add the following to your ~/.mbsyncrc IMAPAccount declaration.

AuthMechs LOGIN

Using LOGIN instead of DIGEST-MD5 is still secure if you have an encrypted connection (IMAPS or STARTTLS). The login will be given plaintext inside the connection.

My mutt cheat sheet

I am learning mutt and I am lost. If you are like me, you may like the following cheat sheet!

I am using it through imap, it may be different with local mailbox.

Case is important !

Change folder : Y
Filter the display : l (for limit) and then a filter like this
~d <2w : ~d for date and <2w for “less than 2 weeks” no space in <2w !
~b “hello mate” : ~b is for body and the string is something to find in the body
~f somebody@zxy.abc : ~f for from and you can make an expression
~s “Urgent” : ~s stands for subject and use a pattern
Delete messages with filter : D with a filter, if you used limit before it will propose by default the filter of limit
Delete a message : d (it will be marked as Deleted)

Deleted messages will be removed when you change the folder or if you exit. Pressing $ can do it manually.
