 This will make VPOP3 find 'smtp.myisp.com' when it looks for the MX servers for 'gmail.com'
-If your ISP requires SMTP authentication, or a different port number you can specify these as well
+If your ISP requires SMTP authentication, or a different port number you can specify these as well by modifying the server name as below. Use:
+  <username>:<password>@<server name>:<port>
+eg, you could have
+  fred:Passw0rd@smtp.myisp.com:587
+Also, you can use wildcards in the domain name part of the line - eg ** *.demon.co.uk**
+===VPOP3 v6.2 and later===
+In VPOP3 v6.2, you can specify multiple lines which match the target domain, VPOP3 will treat those all as having the same priority
+===VPOP3 v6.3 and later===
+Starting in VPOP3 v6.3 you can add more options into the DNS overrides. The first two parts of each line in the overrides is as before - recipient domain, and target mail server, but after that you can specify qualifiers & options
+  - Set priority of the target server - specify ''$priority:<number>''. If you don't specify a priority, then the priority '10' is used.
+  - Check message size - specify ''$size<operator><number>''. If the message size matches the condition, then this line matches
+  - Check message retries - specify ''$retries<operator><number>''. If the number of retries of this message matches the condition, then this line matches
+  - Stop processing the overrides - specify ''$end''. VPOP3 will stop processing the overrides at that point if the recipient domain (and qualifiers, if any) matches.
+If a $size and $retries are both specified, then both must match
+The ''<operator>'' value for the $size and $retries qualifiers are <>, <, =, >, >= and <=. Spaces must not surround the operator
+So, an example line may be:
+  * smtp.myisp.com $retries>=4 $end
+This would tell VPOP3 to send the message to your ISP's SMTP server if a message has already had at least 4 retries
 ====DNS Cache Size====
 This option tells VPOP3 how many recent DNS results it should cache internally. VPOP3 will remember up to this many recent DNS results, but it will also honour the DNS result 'Time to live' (TTL) setting, so entries may be removed from the cache even when the cache isn't full.
