SYNOPSIS

          usage: aiosmtpd [-h] [-v] [-n] [-c CLASSPATH] [-s SIZE] [-u] [-d]
                          [-l [[HOST][:PORT]]] [--smtpscert CERTFILE]
                          [--smtpskey KEYFILE] [--tlscert CERTFILE] [--tlskey KEYFILE]
                          [--no-requiretls]
                          [CLASSARGS ...]

   Options
       CLASSARGS
              Additional arguments passed to the handler CLASS.

       -h, --help
              show this help message and exit

       -v, --version
              show program's version number and exit

       -n, --nosetuid
              This program generally tries to setuid nobody, unless this flag is set.  The setuid call will fail
              if this program is not run as root (in which case, use this flag).

       -c <CLASSPATH>, --class <CLASSPATH>
              Use the given class, as a Python dotted import path, as the handler class for SMTP  events.   This
              class  can  process  received  messages  and  do  other  actions  during  the  SMTP  dialog.  Uses
              aiosmtpd.handlers.Debugging by default.

       -s <SIZE>, --size <SIZE>
              Restrict the total size of the incoming message to SIZE number of bytes  via  the  RFC  1870  SIZE
              extension. Defaults to 33,554,432 bytes.

       -u, --smtputf8
              Enable the SMTPUTF8 extension as defined in RFC 6531.

       -d, --debug
              Increase debugging output. Every -d increases debugging level by one.

       -l <[HOST][:PORT]>, --listen <[HOST][:PORT]>
              Optional  host  and port to listen on.  If the PORT part is not given, then port 8025 is used.  If
              only  :PORT  is  given,  then  localhost  is  used  for  the  hostname.   If  neither  are  given,
              localhost:8025 is used.

       --smtpscert <CERTFILE>
              The  certificate  file  for  implementing  SMTPS.  If given, the parameter --smtpskey must also be
              specified.

       --smtpskey <KEYFILE>
              The key file for implementing SMTPS. If given, the parameter --smtpscert must also be specified.

       --tlscert <CERTFILE>
              The certificate file for implementing STARTTLS. If given, the  parameter  --tlskey  must  also  be
              specified.

       --tlskey <KEYFILE>
              The key file for implementing STARTTLS. If given, the parameter --tlscert must also be specified.

       --no-requiretls
              If specified, disables require_starttls of the SMTP class. (By default, require_starttls is True.)
              Has no effect if --tlscert and --tlskey are not specified.

ENVIRONMENT

       AIOSMTPD_CONTROLLER_TIMEOUT
              How long the main thread will wait (in seconds) until the SMTP thread is ready.
              Default: 1.0
