To deliver messages to several accounts you should use lists. Alias is just one to one, as it is, an alias for an account.

If you use the same alias on more than one account, do you not try to have
two identical email addresses?

I think I found a bug relating account aliases:

Deleting an alias

(BTW: I wonder why the [TAB] stuff is stated in the above syntax since that
is a command, not a cfg file; that's at least confusing in the doc.)

The aliasadd syntax indicates that one can add an alias on a per account

But trying to add the same alias to different accounts fails.

Preventing deleting of messages on the server when fetching by mail client

U.Mutlu — 2013-05-25T23:20:54

Hi,
is it possible with xmail to have a mailbox where the content
cannot be deleted by the user via his mail reader?

This is to allow multiple users to share the same mailbox, a kind of collaboration.
When one user fetches the (new) mails with his mail client then normally
the message gets removed from the server, but in this case that shall not happen.
Is this possible by doing it on the server only (which setting?), as one can't rely on mail client settings.

Thx

Hi Edinilson, thanks for the info.
I must have mixed up the SMTP filters with the other filters.
The xmail documentation is unfortunately a little bit "wild",
it better should be grouped into real sections, and numbered with section
and paragraph numbers for easier reading and referencing.

BTW, does anybody know anything about the whereabouts of the xmail author, Davide?
I haven't seen any posting from him here for more than a year, I think.

How are you dealing with XMail´s files?
Be careful because some files are indexed and you CAN´T edit them directly.

Re: xmail bug: filter return codes wrong

I think that you are missing some points about filters.
Inside mailroot you will find 2 files:
filters.in.tab
filters.out.tab

for example, in filters.in.tab put something like:
"*" *< at >YOUR-DOMAIN "0.0.0.0/0" "0.0.0.0/0" "YOUR-DOMAIN.tab"
After that, you must create a file inside FILTERS dir called: 
YOUR-DOMAIN.tab

So, inside FILTERS\YOUR-DOMAIN.TAB:
you must point to your script, etc, etc

README.TXT will help you with this.

Re: xmail bug: filter return codes wrong

U.Mutlu — 2013-05-24T13:18:09

There is only one flag value, 16, it's optional and means to stop processing
any further filters in the chain, ie. an early-break signal.

I mainly mean the SMPT message filters.
Are the return values 4, 5, 6 (plus +16 to them) not used with this?
As said, in my installation (original v1.27) only 0, 3, and 0+16=16, 3+16=19 is working.

I yesterday tried a filterpgm in filters.out.tab, but it never was called,
not even when mail is destined to a remote server.
When does such a filter normally fire?

And: there is in the MailRoot dir also an empty subdirector named "filters". What is it for?

Thx

Which kind of filter are you asking:
MESSAGE FILTERS
or
SMTP MESSAGE FILTERS
?

Remember that yout must ADD some flags values.
There are some examples in readme.txt

Here I have a filter that add 4 + 16 and returns this value. It´s working 
fine for years.

Re: user permission RA

From readme.txt:

MLUSERS.TAB

If the user is a mailing list this file must exist inside the user account 
subdirectory and contain a list of users subscribed to this

list. The file format is:

"user"[TAB]"perms"[NEWLINE]

where:

user

subscriber email address.

perms

subscriber permissions:

R read.

W write (check done using the 'MAIL FROM:<...>' SMTP return path).

A write (check done using the email address used for SMTP authentication).

Example:

"davidel< at >xmailserver.org" "RW"

"ghostuser< at >nightmare.net" "R"

"meawmeaw< at >kitty.cat" "RA"

xmail bug: filter return codes wrong

U.Mutlu — 2013-05-23T15:54:22

The xmail documentation says:
  If this filters returns '4, 5 or 6' the message is rejected and is
  stopped in its travel. If the filter modifies the message it must return '7'.

But, this info seems to be totally wrong, as only 0 and 3 is working
(plus adding 16 to it for stopping processing other filters).

What happened to xmail?

Anybody know if modifying the mail within a filter is (still) possible in v1.27 ?

I tried to use the xm-spf.pl, but perl reported some errors about

So I managed to write a small filter programm (for filters.pre-data.tab) in C/C++,
and from within that I'm calling the spfquery program with the right parameters.
This works well. I can recommend it.
It needs just 3 parameters (all supplied by xmail to the filter), like so:

I think that the best way to avoid this kind of problem is making an OUTPUT 
filter that insert email headers (from, to, date/time) into a sql table to 
EACH message your XMail sends.
So you can schedule another script in your OS (every 5 minutes, for example) 
that sum these table rows and take some action based on some rules (same 
FROM sending more than 5000 messages a day = BLOCK, same domain sending more 
than 20000 messages a day = BLOCK, etc, etc).

Without this, you will became crazy trying to analyze tons os logs...

I experienced a similar situation some months ago: one of my server 
email owner was sending tons of spam
After figthing with many log files, I have discovered that the hacker 
had been able to hack the mailbox pwd, and he was sending the email 
using smtp autetication method.
You can find the evidence of that inside the smtp log, looking for all 
the authenticated users that are sending email, and find the ones that 
are spam

Re: message logging

Ivo Smits — 2013-05-21T15:45:04

Hello,

It is also possible that someone is sending spam messages directly, not 
via your mailserver. If you have a spam message, you can usually find 
out if this is the case by viewing the e-mail headers (often visible in 
the "raw email source"). Is your mail server listed in the headers (in a 
Received: line)?

You could try to look into the XMail SMTP logs. Their location depends 
on the OS. If the spam mails are listed in these logs, something else is 
sending the emails to your XMail server and your XMail server is 
forwarding these spam messages. In this case you can find the IP address 
and possibly username of the sender. Possibly some account information 
for your mailserver has leaked, or the server may be configured as an 
open relay.

You can also use a tool like wireshark or tcpdump to monitor 
communications on tcp port 25, which would also tell you if your server 
is sending spam mails (if it is sending at that moment).

I hope this helps.

Ivo
