Hmm.  I currently count 230610 messages, which comprise over 11GB of storage.  
But Mail.app is only taking 350MB of real RAM, for a total of 4.04GB of virtual 
memory.  Shared memory is 225MB, and private memory is 114MB.

What I haven’t loaded here is the archive of old mail, which comprises over 
16GB of additional storage.


I do wonder how Mailmate would do with this amount of mail.

There are a lot of things I like about the SaneBox concept, but speaking only 
for myself, I want something running on my own hardware in my own house.

SpamSieve and other Bayesian-style anti-spam filtering tools are good enough 
for that role, but I’m not aware of intelligent adaptive learning systems

regards to stuff I can run myself on my own hardware.

IIRC, Zimbra is a fairly thin wrapper around postfix for the SMTP stuff and

I’ve been doing Internet mail systems administration for over twenty years, and 
in that time I have found that postfix and dovecot are two of the most reliable 
programs in this space.

That’s assuming that you configure them correctly, of course.  ;)


Now, these are CLI programs and do not have a friendly native GUI, nor do they 
have native integration with things like CalDAV, WebDAV, etc

Thank you very much.  However, I think you're the first person, and only known

While I recognize that the community was certainly prickly and divisive, I am

I am convinced that I am better off no longer being an active member of that

Even though *nix boxes can't really get infected with computer viruses per se, 
there are other malware vulnerabilities they do have that can be effectively 
scanned for, and they can certainly provide a good place to do scanning for all 
types of known vulnerabilities.

Few places can afford to take draconian action and say "No e-mail attachments", 
and these days virtually any type of binary file could potentially be infected 
with some sort of malware.  So, if you do have to allow some types of 
attachments through, then I feel it is best to do anti-malware scanning on what 
does pass.

Not that I necessarily pay attention to my own advice all the time, of course.  
;-)

I'm not opposed to MIMEDefang, I just don't know much about it other than what 
I've heard from other people.  Since what I have heard has been pretty good, I 
would certainly be more than willing to take a deeper look into it, if there 
was a specific reason for me to do so.

Otherwise, my preference would be to reach for the tools I already know and not 
have to learn something new in this space.

I'm an old dog, and while I would like to think that I can still learn some new 
tricks, I know that I am slowing down and I want to make sure that I keep at 
least some capacity in reserve for future use.

Moreover, it still wouldn't help with the problem of pushing the rules to be 
executed on the server, so I would really be better off figuring out a way to 
port Mail.app rules into Sieve.

You would have to check the relevant PGP/MIME and S/MIME RFCs, but I believe 
that the standard technique is to take the entire contents of the message (all 
relevant headers included), put that into a text/rfc822 MIME bodypart and sign 
and/or encrypt it.  Of course, that text/rfc822 MIME bodypart could be composed 
of multiple other MIME bodyparts.

On the other end, you reverse the process and display only the signed/encrypted 
headers to the recipient.  The unsigned/unencrypted headers should still be 
available, of course.  If you display both unsigned/encrypted headers as well 
as the signed/encrypted ones, then you need to make sure that there is a visual 
distinction between the two.


But I've seen a couple of guys on this list who know a lot more about RFCs than 
I do.  I'll let them choose whether or not to step forward and identify 
themselves, and provide whatever advice they can.

ISTR that some clients will auto-replace the unencrypted subject line with the 
contents of the encrypted subject (and other headers), once the message is 
decrypted.  And going the other way, they will put in a placeholder like 
"Encrypted subject" into the envelope subject line, which should get replaced 
on the other end when the message gets decrypted.

Was it mutt or elm that did this?  Don't remember -- it's been way too long.

Technically, the signature is encrypted in such a way that you can verify who 
it came from.  If you want to do the verification, you have to be able to use 
the appropriate tools to do the decryption.

One advantage to doing it this way is that you can set up simple standard cron 
jobs to go in and archive messages from the Internet IMAP server to your local 
IMAP server, so that you only keep messages below a certain age on the "public" 
server and everything else is 100% private.


If you set up jobs on the local server to copy down all the remote messages as 
soon as they come in, then you can use your IMAP client to interact exclusively 
with your local IMAP server, and then that will be much, much faster.  And 
these jobs to copy down messages from the remote server could potentially 
operate on other ports, via private VPNs, or tunneled over ssh, so that even if 
you're in a place where you can't normally access your remote e-mail, you could 
still get that copied down to your local server.  Once the messages are copied 
down to the local server, you can purge them from the remote server at your 
convenience.

Of course, I haven't actually done this yet, but I've been meaning to do so for

Maybe this thread will be the impetus I need to make this happen.

Nope.  We're fighting this on the Mailman installation for python.org.  If you 
make no changes, then the IP address of the MTA for the mailing list won't 
match the advertised list for the sending domain, and therefore that message 
will be rejected.

Correct.  We are releasing Mailman 2.1.18 to allow listowners to address this 
issue, but you can also fix it in the MTA before the message gets to the 
mailing list.

A couple of my fellow postmasters for python.org are also well-known postfix 
developers (Patrick and Ralf literally wrote "The Book of Postfix"), and one of 
them is in the process of creating a milter on behalf of the DMARC committee 
that would allow people to easily fix this problem at the MTA.  I would expect 
to see an announcement via the DMARC committee on this subject in the near 
future.

Ironically, I'm at the other end -- I need to be able to read messages that 
others send that are in HTML, even if their MUA was dain-bramaged enough that 
it didn't give me a proper multipart/alternative, with a plain ASCII text

But for what I generate, I'm perfectly happy keeping that to plain ASCII text,

I've heard of Sieve, but although I've been managing Internet mail systems

Right, that was one of the big reasons that I've already enabled the 2.0

However, I have not yet had any chance to look at how they're implemented or

I have a number of accounts, and some of those systems might be able to do 
server-side rules if they were provided, but they don't give me any sort of way 
to create those rules.  If MailMate could give me a way to create the 
server-side rules and then upload them, I'd be fine going through the process 
of doing the translation.

But I can guarantee you that not all of the systems will have the ability to 
apply server-side rules, and "smart mailboxes" are -- at best -- only a partial 
solution to this problem.

It does really pain me to have to apply these rules on the client side, 
especially since this is one of the things that seems to go so horribly wrong 
with Mail.app [0], but I don't see an alternative at the moment.







[0] Mail.app frequently hangs on a given account on one server and stops any 
further processing of any rules for any accounts on any server.
