Failed POP3 login attempts from

While checking the mail log file, /var/log/maillog, on an email server today, I noticed an attempted login from an IP address in an address range I didn't recognize. The entry in the log file contained the following text:

dovecot: pop3-login: Disconnected (tried to use disallowed plaintext auth): user=<>, rip=

I checked the country associated with the IP address ( with geoiplookup (you can install the GeoIP package on a CentOS Linux system with yum install GeoIP) and found it was an address assigned to an entity in Great Britain.

$ geoiplookup
GeoIP Country Edition: GB, United Kingdom
