hello list
Turns out I use a webmail (horde) in my workplace but apparently has a
bug, somehow are generating large numbers of messages to various
servers on the internet, yahoo, aol, hotmail and others. to keep me
look like an open relay server.
This webmail delivers to a local server then sent messages to the same
given to one of my mx servers for final delivery.
desire to limit the local server that only accepts mail from valid
accounts which have a list, so there is no problem, I've done and it
works when I do a telnet to localhost and use SMTP commands: MAIL FROM
and RCPT TO this limit, but rather rejected if the address placed in
the mail from is not on the list.
smtpd_sender_restrictions =
check_sender_access hash: / etc / postfix / recipients,
reject_non_fqdn_sender, reject_unknown_sender_domain, reject
but in actual practice when I generate the messages postfix is
acceptable, I may be doing wrong???
this is my log
