one of our outbound mailers is listed in spamrl.com - which is odd, and it isn't listed in anything else right now.

Simple serious question: why do you care?

Easy answer: because when I tried to email somebody this morning my message bounced because of the SpamRL listing.

Looks like webmail provider  siteprotect.com uses them:

                The mail system

<office@[redacted] host mx.siteprotect.com[64.26.60.135] said: 550
    The sending IP (64.68.200.34) is listed 
onhttps://spamrl.com&e=e7eb7067&h=55a584b4&f=y&p=y   as a source
    of phishing. (in reply to end of DATA command)

granted - siteprotect website looks like it dates back from the 90's - but I still ran into a block with this RBL in real-world circumstances and when I check our system mailer logs, there are other systems using it, including:

web-dns1.com
mtaroutes.com
secure-mailgate.com
cleanmx.pt

Most of these look like very old antispam gateway systems but they are evidently still in use and using this RBL
