Error while Sending mail

[hamed]

hi all,
when i want to send mail from open-xchange, when i click send button, a red line appear on the screen :
Internal error: Could not connect to SMTP host: localhost, port: 25, response: -1 (MSG-0020,619657516-12)

and in /var/log/mail.log i have :

Aug 26 10:30:03 localhost postfix/smtpd[16713]: connect from localhost.localdomain.com[127.0.0.1]
Aug 26 10:30:03 localhost postfix/smtpd[16713]: fatal: non-null host address bits in "127.0.0.1/25", perhaps you should use "127.0.0.0/25" instead

and this is my main.cf file :

... Any idea??
Thanks in advance

Hi,

tried to change

mynetworks = 127.0.0.1/25
to
mynetworks = 127.0.0.0/25 ?

i'm not sure you need this parameter at all if you want to send E-Mail from external computers also... this is my main.cf:

smtpd_banner = $myhostname - ESMTP Service
mailbox_transport = lmtp:unix:/var/run/cyrus/socket/lmtp

virtual_alias_domains = mysql:/etc/postfix/ox_domains.cf
virtual_alias_maps = mysql:/etc/postfix/ox_user_aliases.cf, mysql:/etc/postfix/ox_aliases.cf, mysql:/etc/postfix/ox_resource_aliases.cf, mysql:/etc/postfix/ox_group_aliases.cf

smtpd_sender_restrictions = check_sender_access mysql:/etc/postfix/ox_externaldomaincheck.cf
smtpd_restriction_classes = local_only
local_only = check_recipient_access mysql:/etc/postfix/ox_domains.cf, reject

smtpd_recipient_restrictions = check_sender_access mysql:/etc/postfix/ox_senderrestrictions.cf, permit_sasl_authenticated, permit_mynetworks, reject_unauth_destination
smtpd_tls_cert_file = /etc/ssl/certs/eecert.pem
smtpd_tls_key_file = /etc/ssl/private/eekey.pem
procmail_destination_concurrency_limit = 1
procmail_destination_recipient_limit = 1
maximal_queue_lifetime = 1d
alias_maps = $alias_database
bounce_queue_lifetime = 1d

Hi Martin,
I have changed 'my_network' parameter to 127.0.0.0/25 & now it's working, thanks
i have a question here! what does 127.0.0.0 exactly mean?!

Thanks in advance

[Martin Heiland]

127.0.0.0 is a network address which specifies where E-Mail is accepted from. Please consult the postfix documentation for more information about that parameter.
