Transmission on this port requires AUTH, therefore users sending on that port must configure their mail clients appropriately to ensure that their connections are authenticated. Further, because some ISPs block port 25, your remote users might be able to circumvent that restriction by using the MSA port instead. If you do not wish to designate an MSA port then set the value to &quot;0&quot; to disable it.<\/span><\/p>\n\r<div style=\"text-align: left; text-indent: 0; padding: 0 0 0 0; margin: 0 3.0625rem 0.8750rem 3.0000rem;\"><table style=\"background-color:#ffffe6; border:solid thin #000000; border-spacing:0;\">\n\r<tr>\n\r<td style=\"vertical-align:top; width:3.1250rem; height:3.1250rem; padding:0.3125rem; border:none\"><p class=\"p_NoFormat\"><img style=\"margin:0;width:3.1250rem;height:3.1250rem;border:none\" src=\".\/images\/lightbulb_on_50_yback.gif\"\/><\/p>\n\r<\/td>\n\r<td style=\"vertical-align:top; padding:0.3125rem; border:none\"><p class=\"p_Notes\"><span class=\"f_Notes\">Connections to the MSA port are exempt from PTR and reverse lookups, Host and IP screening, the IP Shield, and Tarpitting.
