Now, you can reply chat messages via email. It supports full formatting like inline, multiline, bold, italics, etc.

Switch from IMAP to POP

  • Before you switch from IMAP to POP over the same email address, you must empty all the folders. Keeping all emails results in duplicate messages, because all those messages in POP are treated as new messages.


  • Currently, only emails in English are supported, or at least the quote On <date>, <author> wrote: is in English.

An Email body in languages other than English may also work until and unless On <date>, <author> wrote: is in English or a copy of older email is removed manually.

  • Only text messages are supported; attachments are not supported yet.

Known issues

Quoted headers

Quoted headers aren't picked up if the email client breaks it up into multiple lines.

GMail breaks up any lines over 80 characters for you.

On <date>, <author>
> blah

Not to mention that we are searching for on and wrote. It doesn't work with other languages.

Possible solution: while replying, remove everything else than your actual message.

Weird signatures

Lines starting with - or _ sometimes mark the beginning of signatures:



But some users change this convention:


Mr Rick Olson
Galactic President Superstar Mc Awesomeville

* Note: blah blah blah                                            *


Your message wasn't posted? Did you get an Invalid Email in the Admin console? This most likely means that the email format was not as expected. Maybe you were blocked or the message/room was deleted.
