Fix for issue where 2.0.0 was always being set even if it should not have
been set.
Rev 1.21 7/27/2004 7:18:20 PM JPMugaas
Fixed the TIdReplySMTP object as per Bas's suggestion. He told me that we
were overriding the wrong object.
I also fixed the Assign so it will work properly.
Rev 1.20 7/24/04 1:04:48 PM RLebeau
Bug fix for TIdReplySMTP.AssignTo(). The logic was backwards
Rev 1.19 5/31/04 12:47:02 PM RLebeau
Bug fixes for TIdSMTPEnhancedCode.AssignTo() and TIdReplySMTP.AssignTo()
Rev 1.18 5/18/04 2:39:52 PM RLebeau
Changed TIdRepliesSMTP constructor back to using 'override'
Rev 1.17 5/18/04 11:21:54 AM RLebeau
Changed TIdRepliesSMTP constructor to use 'reintroduce' instead
Rev 1.16 5/16/04 5:27:32 PM RLebeau
Added TIdRepliesSMTP class
Rev 1.15 2004.02.03 5:45:44 PM czhower
Name changes
Rev 1.14 2004.01.29 12:07:54 AM czhower
.Net constructor problem fix.
Rev 1.13 2004.01.23 10:09:54 PM czhower
REmoved unneded check because of CharIsInSet functinoalty. Also was a short
circuit which is not permitted.

Undid a set change that didn't work.
Rev 1.11 1/22/2004 4:51:40 PM SPerry
fixed set problems
Rev 1.10 1/3/2004 8:05:54 PM JPMugaas
Bug fix: Sometimes, replies will appear twice due to the way functionality
was enherited.
Rev 1.9 2003.10.18 9:42:14 PM czhower
Boatload of bug fixes to command handlers.
Rev 1.8 10/17/2003 12:58:54 AM DSiders
Added localization comments.
Rev 1.7 2003.09.20 10:38:42 AM czhower
Bug fix to allow clearing code field (Return to default value)
Rev 1.6 6/5/2003 04:54:24 AM JPMugaas
Reworkings and minor changes for new Reply exception framework.
Rev 1.5 5/30/2003 8:46:28 PM BGooijen
