Hallo,
auf einem Server dauert es immer einige Sekunden zwischen dem
Verbindungsaufbau und dem Senden des Banner des Servers.
Da mir leider jede Idee fehlt, woran das liegen könnte muss ich mich mal
an euch wenden.
Kennt jemand das Problem?
Hier mal meine main.cf:
inet_interfaces= xxx.xxx.xxx.xxx, 127.0.0.1
myhostname= mail.example.com
relay_domains=
append_dot_mydomain= no
smtpd_banner= $myhostname ESMTP running Postfix on Debian/GNU
mydestination= $myhostname
mynetworks= localhost, 127.0.0.1
#debug_peer_list= 127.0.0.1
#smtpd_peername_lookup = no
## Virtual Mailboxes
virtual_alias_maps= proxy:mysql:/etc/postfix/mysql/virtual_forwardings.cf
virtual_mailbox_domains= proxy:mysql:/etc/postfix/mysql/virtual_domains.cf
virtual_mailbox_maps= proxy:mysql:/etc/postfix/mysql/virtual_mailboxes.cf
virtual_mailbox_base= /srv/mail
virtual_uid_maps= proxy:mysql:/etc/postfix/mysql/virtual_mailboxes_uids.cf
virtual_gid_maps= proxy:mysql:/etc/postfix/mysql/virtual_mailboxes_gids.cf
## SASL
smtpd_sasl_auth_enable= yes
smtpd_sasl_security_options= noanonymous
broken_sasl_auth_clients= yes
## Restrictions
smtpd_recipient_restrictions=
reject_unknown_sender_domain,
reject_non_fqdn_sender,
reject_non_fqdn_recipient,
permit_sasl_authenticated,
# reject_non_fqdn_hostname,
# reject_invalid_hostname,
permit_mynetworks,
reject_unknown_recipient_domain,
reject_unauth_destination,
reject_unlisted_recipient,
reject_rbl_client bl.spamcop.net
