\nSubject: Event 24391509 – OUTBOUND SMTP PORT 25 CHANGES<\/p>\n
=================================================================
\n\/ Event Description \/
\nStarting 02\/01\/2016, SoftLayer will be implementing additional measures to stop malicious internet actors that look to the SoftLayer platform as a resource for them. One of the measures we\u2019re implementing is a traffic filter to block outbound TCP port 25, which will prevent bare metal and virtual server instances from sending direct outbound email.<\/p>\n
We ask that you review your systems and applications to determine if they are sending direct outbound email. Once these changes are implemented, your public IP addresses will cease to have access to send traffic outbound via TCP port 25, and any direct email which is created by your systems will need to route through an SMTP relay (typically TCP port 587 or 465).<\/p>\n
SoftLayer has partnered with SendGrid and is providing each customer with an account at no cost which allows sending of up to 25,000 emails\/month. More details about this change, and how to implement the SendGrid service, can be found at http:\/\/knowl Should you have an account manager, please feel free to contact them should you have any concerns.
