In addition to network upgrades, free spam filtering and anti-virus software, AT&TIS is implementing outbound email SMTP port controls to ensure that its network is as reliable as possible for our Members. As announced in the September 2004 Member newsletters, AT&TIS began filtering direct outgoing email connections using Port 25 (SMTP) to non-AT&TIS/Yahoo mail servers from Members using dynamic High Speed Internet and Dialup connections. Port 25 filters are widely used by many ISPs to combat junk email and spam from mis-configured and virus-infected computers. AT&TIS Members using AT&TIS or Yahoo! mail servers for outgoing email are not impacted by this filter. Incoming email connections are also not affected. Members using a private company, university or hosting provider mail server will not be able to send outgoing email from dynamic High Speed Internet and Dialup connections until one of the following actions are taken: 1. Contact your mail hosting provider for information about using Port 587 for sending authenticated outgoing email. Since December 1998, Port 587 has been the Internet standard (RFC2476) port for authenticated email submission for mail clients and is supported by most major mail hosting providers. 2. Contact your mail hosting provider for information about using other alternative access methods to connect to their mail server, such as VPN, Web mail or Outlook Web Access to send outgoing email. 3. AT&TIS Members may send outgoing mail messages through AT&TIS mail servers, even if they use other email domains in their mail address, by converting their Outgoing mail (SMTP) to use AT&T mail servers . Members should not change their Incoming mail server (POP3/IMAP). 4. AT&TIS Members who can not use any of the preceding alternatives may request that AT&TIS remove the SMTP port 25 filter from the Member's account. To request removal of the filter, use the Abuse of Service form at to contact our Abuse team and choose the "Opt-Out Port 25" under Abuse Type. Enter your account Member ID (also called your AT&TIS PPPOE Login ID or User ID) to opt-out. If you have multiple AT&TIS accounts you want to opt-out, please submit a separate form for each Member ID. Do not enter your email addresses from the other mail hosting provider. You should expect that it will take AT&TIS 12-24 hours to process your request. After receiving a confirmation email, sent to the AT&TIS Member account ID being opted-out, you will need to logoff the AT&TIS network and turn off your DSL router or modem for 1 minute to remove the filter. You should then turn your modem and system back on and log in using the normal procedure. The SMTP Port 25 filter does not affect Members using Web mail to any mail provider, VPN connections to a private company or university mail server, dedicated (e.g. T1/T3 or Frame-Relay) or "static" IP addresses. Additional Resources & Updates These additional resources may be used if there is a possible issue with the SMTP port controls upgrade. • How can I locate and verify my email settings?
