501 5.5.4 Invalid arguments

[bguerreiro]

Hi all,
I sometimes get the following error:

<mail.removed@domain.com>: host server.domain.com[www.xxx.yyy.zzz]
said: 501 5.5.4 Invalid arguments (in reply to MAIL FROM command)

This happens only with users that have the following internet address format with omshowu:
Internet Address : "Username Removed" <username.removed@domain.pt>=username.removed@scalix.domain.pt

Any ideas?
Best Regards

[florian]

does the friendly name part contain any non-ascii characters in these cases?

thx,
f.

Hi Florian.

does the friendly name part contain any non-ascii characters in these cases?

thx,
f.

No.
And it only happens with some recipients, not all.
I Also tested it by telnetting to the server
[root@mx ~]# telnet www.xxx.yyy.zzz 25
Trying www.xxx.yyy.zzz...
Connected to www.xxx.yyy.zzz (www.xxx.yyy.zzz).
Escape character is '^]'.

250 server.domain.com Hello [zzz.yyy.xxx.www]
MAIL FROM:"Username Removed" <username.removed@domain.pt>

I'm almost sure that the Exchange is to blame, but this didn't happen before Scalix was in place.

TIA.

You're completely right - MAIL FROM should not contain the display name (as per RFC2821). However, I just checked and found that Scalix does not generate it and conforms to the standard. This is one of my test users and the SMTP conversation that takes place here:

Also, afaik, sendmail on Linux (through which this goes), does not put the display name into the MAIL FROM conversation. Could it be that at your site there is another relay in the outgoing path that constructs the MAIL FROM from the "From:" header attribute (which contains the friendly name - that's correct and in accordance with RFC2822) and does not strip it? What kind of box are you using on your outgoing path.

As the error is returned from the receiving system on the 'net, most likely the last relay in your outgoing path is at fault.

The reason why this might not have happened before Scalix is possibly that your old exchange system did not bother putting the display name in the From: header, so the relay would not convey it into the MAIL FROM.

Cheers,
Florian.

HI again Florian,
Our DMZ relay is running postfix.
But here comes the really hairy part.
This is a telnet session to my home server (also running postfix):

[root@mx ~]# telnet home.domain.org 25
Trying www.xxx.yyy.zzz...
Connected to home.domain.org (www.xxx.yyy.zzz).
Escape character is '^]'.
220 home.domain.org ESMTP Postfix
helo domain.pt
250 home.domain.org
MAIL FROM:"Username Removed" <username.removed@domain.pt>
555 Unsupported option: <username.removed@domain.pt>

Yet, this machine get's every mail sent by users that have issues.

I'm lost.

[florian]

Hi Bruno,

i guess that is not what i meant.

No machine MUST actually accept the syntax as it is incorrect.

However, what I am saying is is that as the errors your're getting in the NDN are external errors, it must be the Postfix box that is generating the wrongly-formatted mail-from commands.

this would be independent of scalix. scalix is NOT sending the MAIL FROM with the display name.

is this the latest version of postfix? can you capture outgoing SMTP conversation on the postfix box somehow?

Florain.

[bguerreiro]

HI Florian,
I do understand that no machine should accept, what confuses me is that only some receiving machines don't.
About the conversations here goes.
Scalix to our postfix:

> unknown[zzz.yyy.xxx.www]: 220 mx.domain.pt ESMTP Postfix
< unknown[ zzz.yyy.xxx.www]: EHLO scalix.domain.pt
> unknown[ zzz.yyy.xxx.www]: 250-mx.domain.pt
> unknown[ zzz.yyy.xxx.www]: 250-PIPELINING
> unknown[ zzz.yyy.xxx.www]: 250-SIZE 7000000
> unknown[ zzz.yyy.xxx.www]: 250-ETRN
> unknown[ zzz.yyy.xxx.www]: 250-ENHANCEDSTATUSCODES
> unknown[ zzz.yyy.xxx.www]: 250-8BITMIME
> unknown[ zzz.yyy.xxx.www]: 250 DSN
< unknown[ zzz.yyy.xxx.www]: MAIL From:<username.removed@domain.pt> SIZE=1336 ENVID=H0000089000be5fb.1170248569.scalix.lx.domain.pt RET=HDRS
extract_addr: input: <username.removed@domain.pt>

Our postfix talking to my home postfix:

> mx.domain.pt[www.xxx.yyy.zzz]: 220 domain.org ESMTP Postfix
< mx.domain.pt[www.xxx.yyy.zzz]: EHLO mx.domain.pt
> mx.domain.pt[www.xxx.yyy.zzz]: 250-domain.org
> mx.domain.pt[www.xxx.yyy.zzz]: 250-PIPELINING
> mx.domain.pt[www.xxx.yyy.zzz]: 250-SIZE 20480000
> mx.domain.pt[www.xxx.yyy.zzz]: 250-VRFY
> mx.domain.pt[www.xxx.yyy.zzz]: 250-ETRN
> mx.domain.pt[www.xxx.yyy.zzz]: 250 8BITMIME
< mx.domain.pt[www.xxx.yyy.zzz]: MAIL FROM:<username.removed@domain.pt> SIZE=1553

So, i don't think either Scalix or Postfix are using the friendly name in the MAIL FROM: header.

I can add an Exchange SMTP server in between Scalix and postfix just to do some testing, if you think that would help.

TIA.
Bruno

[florian]

well, but can you also get a log of the conversation where this is sent from one of the users where the problem happens?

on the receiving side, an MTA can chose to ignore additional elements and still accept the conversation........

Hi Florian,

As requested.
> unknown[www.xxx.yyy.zzz]: 220 mx.domain.pt ESMTP Postfix
< unknown[www.xxx.yyy.zzz]: EHLO scalix.domain.pt
> unknown[www.xxx.yyy.zzz]: 250-mx.domain.pt
> unknown[www.xxx.yyy.zzz]: 250-PIPELINING
> unknown[www.xxx.yyy.zzz]: 250-SIZE 7000000
> unknown[www.xxx.yyy.zzz]: 250-ETRN
> unknown[www.xxx.yyy.zzz]: 250-ENHANCEDSTATUSCODES

AAAAAAAAAzP3JzSU6T0q17kkTkrs8jsKAAAAQAA ... @domain.pt RET=FULL

From a quick analisys I can see that message ID has some diferences, as one indicates scalix.lx.domain.pt and the other just indicates domain.pt
Also the RET values are different.
Another thing. The message is refused only when the sender ISN'T using the Outlook connector, but IMAP/SMTP.

Best regards,
Bruno

[florian]

Hi Bruno,

now I am confused - is this your outgoing postfix relay talking to some external box or is this scalix talking to the postfix box?

Florian.

[bguerreiro]

Hi,
Sorry for the added noise.
This is Scalix talking to postfix.
The log is from the Postfix box.

[florian]

Hi Bruno,

what we need is the log postfix talking to the outside world, because it seems that it is the recipients MTA that is actually rejecting the message, not your postfix.

if it is as you say, obviously the two dialogs coming from the user using swa and using outlook to compare would be useful.

Florian.

[bguerreiro]

HI again Florian,

Hi Bruno,

Yes, Postfix never rejected the messages.
I've used ethereal. Hope this helps.

zzz.yyy.xxx.www is the receiving Exchange
www.xxx.yyy.zzz is the sending postfix

Florian.

Is the same user connecting either with Outlook Connector or thru IMAP/SMTP.
I've asked the user to test with SWA, but haven't got any feedback yet.

Hi Florian,
New info, the server in this case is Sendmail, so not Exchange specific.
The following capture is from a mail sent thru SWA.

[florian]

did you say this is SWA vs IMAP/SMTP? Didn't you mention Outlook earlier? Or is this Outlook without Scalix Connect and using IMAP/SMTP? If not, what IMAP/SMTP client was this sent from?

Cheers,
Florian.
