I built a mail server using Postfix and Dovecot.
I can send and receive emails without any problems.
I often want to quickly check the contents when connecting with ssh, but I don't know how to open the file correctly.
Mail received is stored in ~/Maildir/new/, but is garbled when opened with the cat command.
How can I check not only my mail, but also when I am a root user and want to check other users' mail?
This may be an elementary question, but I couldn't find it after searching it well, so please let me know.
Thank you for your cooperation.
If it is CentOS 6,7 mailx, I think you can read it in mailx-f~/Maildir.
Is garbled characters due to differences in encoding, or is Base64, Quoted-printable displayed as it is?
In the former case, the charset is set correctly in the mail header, and if the shell environment variable and terminal emulator encoding are combined, I think I could read it by mailx.
(Example) LANG=ja_JP.UTF-8mailx-f~/Maildir
Pager with character code conversion function, specifically lv, nkf, iconv, etc.
If you are using Dovecot and have root privileges, you may want to search and retrieve it by doveadm (1).
Retrieve all body parts of user alice new mail messages:
#doveadm search-ualice NEW\
| while read mailbox_guide;do
doveadm fetch-ualice body mailbox-guid$mailbox_guiduid$uid
done\
;
See the online documentation doveadm-search (1), doveadm-search-query (7), doveadm-fetch (1).
