Dear Maintainer,

prayer could not be used with email addresses as user login.
The @ character completely confuse the session and front-end
process communication :
A socket is created with a @ character but the front-end use the
@ character as a separator between the socket name and the command
to pass it into.

Could be downgraded to a feature request, but get it unusable in
most modern imap config/use.

Best regards,
Emmanuel.

Ok, I implemented minimum required support to get it working with
email address as username.
It is enough to log in and navigate in the mailbox.
It surely have some limitations (I did not check email sending) but
now perfectly suit my needs (simple and self contained webmail
to consult and delete emails).

Emmanuel.
----------
email_as_login.patch:

Description: add basic support to use email address as username/login
  Username:backenPID was limited to 32 bytes. Bump to 64 to be usable with
  email address.
  @ was used unconditionally as a delimiter to split the request int the argv
  array. As many proxy/reverse-proxy rewrite %40 as @, do not split on @
  if we are processing the username (second field).
