Actually, AOL SMTP servers are not a secret (they really couldn't be,
when you come right down to it) but their POP services (the method by
which standard RFC compliant messaging apps pick up you mail) are well
cloaked.

Here's the NSLookup output for SMTP delivery to AOL:

> aol.com
Non-authoritative answer:
Name:    aol.com
Addresses:  205.188.160.120, 64.12.149.25, 64.12.187.24, 205.188.145.213

 set type=all
> aol.com
Non-authoritative answer:
aol.com internet address = 205.188.145.213
aol.com internet address = 205.188.160.120
aol.com internet address = 64.12.149.25
aol.com internet address = 64.12.187.24
aol.com nameserver = dns-01.ns.aol.com
aol.com nameserver = dns-02.ns.aol.com
aol.com nameserver = dns-06.ns.aol.com
aol.com nameserver = dns-07.ns.aol.com

aol.com nameserver = dns-01.ns.aol.com
aol.com nameserver = dns-02.ns.aol.com
aol.com nameserver = dns-06.ns.aol.com
aol.com nameserver = dns-07.ns.aol.com
dns-01.ns.aol.com       internet address = 152.163.159.232
dns-02.ns.aol.com       internet address = 205.188.157.232
dns-06.ns.aol.com       internet address = 149.174.211.8
dns-07.ns.aol.com       internet address = 64.12.51.132

> set type=mx
> aol.com
Non-authoritative answer:
aol.com MX preference = 15, mail exchanger = mailin-02.mx.aol.com
aol.com MX preference = 15, mail exchanger = mailin-03.mx.aol.com
aol.com MX preference = 15, mail exchanger = mailin-04.mx.aol.com
aol.com MX preference = 15, mail exchanger = mailin-01.mx.aol.com

aol.com nameserver = dns-01.ns.aol.com
aol.com nameserver = dns-02.ns.aol.com
aol.com nameserver = dns-06.ns.aol.com
aol.com nameserver = dns-07.ns.aol.com
mailin-02.mx.aol.com    internet address = 64.12.137.184
mailin-02.mx.aol.com    internet address = 64.12.138.89
mailin-02.mx.aol.com    internet address = 64.12.138.120
mailin-02.mx.aol.com    internet address = 64.12.136.89
mailin-02.mx.aol.com    internet address = 64.12.136.121
mailin-02.mx.aol.com    internet address = 64.12.137.89
mailin-03.mx.aol.com    internet address = 64.12.138.57
mailin-03.mx.aol.com    internet address = 64.12.138.120
mailin-03.mx.aol.com    internet address = 64.12.136.217
mailin-03.mx.aol.com    internet address = 64.12.136.249
mailin-03.mx.aol.com    internet address = 64.12.137.121
mailin-03.mx.aol.com    internet address = 64.12.137.152
dns-01.ns.aol.com       internet address = 152.163.159.232
dns-02.ns.aol.com       internet address = 205.188.157.232
dns-06.ns.aol.com       internet address = 149.174.211.8
dns-07.ns.aol.com       internet address = 64.12.51.132

At the time I did the lookup, these were the 4 preferred Mail (MX)
servers in operation, all with equal prioritization (15):
aol.com MX preference = 15, mail exchanger = mailin-02.mx.aol.com
aol.com MX preference = 15, mail exchanger = mailin-03.mx.aol.com
aol.com MX preference = 15, mail exchanger = mailin-04.mx.aol.com
aol.com MX preference = 15, mail exchanger = mailin-01.mx.aol.com

As it turns out, these prefs are also 'clustered' or proxies for a
gaggle of mail servers behind these addresses. Check out this connection
string from connecting to mailin-02:
