[Guest]

I configure the smtp proxy in EFW 2.4 It works with out issue two or three days, after that the mails stop coming in and in the web dashboard the SMTP proxy appears as OFF. and   in the proxy configuration appears enabled.
the maillog start to fill up with the following error:

Sep 22 08:58:03 ptco00it014fw postfix/smtpd[18813]: warning: connect to 127.0.0.

The stats for the SMTP Proxy in the Dashboard are as follow.

                                         Hour   Today
mails received             17       1325
clean mails received    14       963
spam mails received    1         219
viruses found              0            0
mails rejected             1882    67244


Any Ideas of what to do  because the SMTP service for me its not reliable.
Any help is appreciated because the antispam in Endian do miracles in my mail traffic.

Best regards.
