24 Once I get Dovecote set up, that could be a option.  Sounds like a good
25 one at that.  ;-)

42 If I understand you correctly, I have filters set up for different
43 messages.  Gentoo-user for example gets sent to a Gentoo-user folder.  I
44 have similar set up for most anything that I get on a regular basis;
45 ebay, Amazon, bank, family, friends, gentoo lists or forums and lots of
46 others.  Seamonkey comes with a spam filter and most go to trash as I
47 have it set to do.  Thing is, I'd rather not get them because who knows
48 what mischief they can do or what can be attached.  I have Seamonkey set
49 to not load anything, except for highly trusted sites, but still, I
50 don't like them sending me their junk.  In all honestly, it doesn't do
51 them any good because of my own policy.  I never click on ads, not since
52 2003.  While I use adblock to block most stuff, even if a ad gets
53 through, I never click on them.  As a matter of fact, there are some
54 that have paid for some really annoying ads on sites that I've blocked
55 because of their ads.  I don't do business with them.  Why reward bad
56 behavior??

82 Well, for the moment, I want to use it for gmail that I'm posting with. 
83 My reason for this, Seamonkey is in a iffy state.  I've already started
84 using Firefox and containers for most other things but use Seamonkey
85 mostly for emails.  My hope, set up something local so that I don't lose
86 any older emails and then be able to access those emails with whatever
87 web browser or other tool I want, like Firefox.  Of course, I'd want to
88 be able to send email as well.  Maybe this is a bigger task than I think
89 it is.  Either way, I have Dovecote installed, think it is working but
90 no idea what to do with it. 
92 Thanks.
