Subject Re: Matcher and Mailet could be invoked twice for a single mail
Date Sun, 03 Aug 2014 07:47:19 GMT
Hi Syin,

You don't bother us, on the contrary, you are helpful.
(Btw, text format is easier to work with on the mailing list).

I must admit I don't have an answer and I doubt about the behavior.

@Stefano Any idea on this (cfr your answer on
http://markmail.org/message/pyhd4wgyyheqmgbc)

@Norman Any input on this (as you wrote that code).

Please see the initial html mail on
https://issues.apache.org/jira/secure/attachment/12656845/2014-07-21_175109.png

Thx,
Eric
