• postfix smtpd rejecting mail from outside network match_list_match: no match

  - by Loopo

  My postfix (V: 2.5.5-1.1) running on ubuntu server (9.04) started to reject mail arriving in from outside about 2 weeks ago. Doing a "manual" session via telnet shows that the connection is always closed after the MAIL FROM: [email protected] line is input, with the message "Connection closed by foreign host." Doing the same from another client inside the LAN works fine. In the log files I get the line "lost connection after MAIL from xxxxx.tld[xxx.xxx.xxx.xxx]" This is after some lines like: match_hostaddr: XXX.XXX.XXX.XXX ~? [::1]/128 match_hostname: XXXX.tld ~? 192.168.1.0/24 ... match_list_match: xxx.xxx.xxx.xxx: no match which seem to suggest some kind of filter which checks for allowed addresses. I have been unable to locate where this filter lives, or how to turn it off. I'm not even sure if that's what's causing my problem. Connections from inside the LAN don't get disconnected even though they also show a "match_list_match: ... no match" line. I didn't change any configuration files recently, below is my main.cf as it currently stands. I don't really know what all the parameters do and how they interact. I just set it up initially and it worked fine (up to recently). smtpd_banner = $myhostname ESMTP $mail_name (GNU) biff = no readme_directory = no # TLS parameters smtpd_tls_cert_file=/etc/ssl/certs/server.crt smtpd_tls_key_file=/etc/ssl/private/server.key #smtpd_use_tls=yes smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtp_sasl_auth_enable = no smtp_use_tls=no smtp_sasl_password_maps = hash:/etc/postfix/smtp_auth myhostname = XXXXXXX.com alias_maps = hash:/etc/aliases alias_database = hash:/etc/aliases myorigin = /etc/mailname mydestination = XXXX.XXXX.com, XXXX.com, localhost.XXXXX.com, localhost relayhost = XXX.XXX.XXX.XXX mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 192.168.1.0/24 mailbox_command = procmail -a "$EXTENSION" mailbox_size_limit = 0 recipient_delimiter = + inet_interfaces = all smtpd_sasl_local_domain = #smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_sasl_authenticated_header = yes broken_sasl_auth_clients = yes smtpd_recipient_restrictions = permit_mynetworks,permit_sasl_authenticated,reject_unauth_ when checking the process list, postfix/smtpd runs as smtpd -n smtp -t inet -u -c -o stress -v -v Any clues?

• ms excel find and replace @ symbol results in broken formula

  - by Loopo

  I'm trying to search and replace in excel, the column is formatted as 'Text'. Find: [@ replace with: @ Whenever this finds a match at the start of a cell i.e the cell contents start with [@ and tries to replace that with @ the result is an error 'This function is not valid' I guess that since the @ operator is for references, this is causing the cell to be interpreted differently (not as text anymore) How do I make this replacement work? Copy/paste into another program is not a good option because some of the cells contain line-breaks.
