Zend_Mail and Microsoft Exchange Servers

[Justin Hendrickson-2]

Has anyone experienced problems with sending attachment with Zend_Mail
to MS Exchange servers? I consistently get emails from them saying the
attachment on the email I sent was corrupt.

I initially thought the PDF was corrupt, so I started saving a copy of
it before emailing it. The PDF opens fine, and weirder yet, sending
the attachment with my email client (Evolution) works fine, no
corruption issues.

I'd test this myself, but I don't have an MS Exchange server to run
the tests on. I might be able to send a couple more emails to one of
the users, but they're typically too busy to expect any kind of
reasonable turn around time.

Some javascript/style in this post has been disabled (why?)

There have indeed been issues in this area; perhaps there still
are.  What release of Zend_Mail sources do you use?

This project is a bit old and never got upgraded, so I'm using ZF 0.7.0.

I'm going retry sending an email with an attachment to the client
using 0.7.0 and 1.0.3 and see if there's any difference.

I just confirmed that Zend_Mail in 0.7.0 and 1.0.2 both failed to send
the attachment correctly.

I'm looking at raw copies of each email and they look mostly identical
(minus timestamps, ids, mime boundaries and such).

I'm going to create a new test with 1.0.3 in a minute here.

I tested out Zend_Mail from 1.0.3 and the trunk and got the same result.

I sent myself a copy of each mail, saved each of their raw source, and
diff'ed them. 0.7.0, 1.0.2 and 1.0.3 are pretty much all the same,
excluding the previously mentioned differences.

I'm going to have to wait until tomorrow to send out another batch of
tests, unless we can find someone with an MS Exchange server tonight.

In the mean time, I'm going to create a set of test scripts that use
Zend_Mail 0.7.0, 1.0.2, 1.0.3, trunk, as well as the latest version of
PHPMailer and PEAR::Mail. Hopefully one of those will work and we'll
have something to look at.

Justin,

What happens if you diff the exchange attachment vs. the one you send  
yourself (which, obviously doesn't go through exchange?)

Maybe figuring out what's happening with the attachment might help  
figure out where it is?  Also, does it happen with any other kinds of  
attachments?  Have you tried with like a zip or tarball, or maybe a  
word document of some sort?

Regards,
Eric

Hi,

i have a bunch of Exchange servers here, so please provide me a set of test
scripts to check the issue.

Unfortunately, all the people that having problems with attachments
are also Outlook 2003 users. In order to get the full source of an
email with Outlook 2003, you have to make a registry change. Normally
I'd just call them up and do some troubleshooting with them, but
they're not direct customers (these are invoices PDF's I'm sending
them) and they're very busy, so they're not very eager to assist me.

I just sent off my test scripts to Eric Coleman, so hopefully he can
reproduce the bug with those and we can identify the bug.

I just sent out another batch of tests and all versions (0.7.0, 1.0.2,
1.0.3, trunk) of Zend_Mail had bad attachments. I also sent two tests
using PEAR::Mail and PHPMailer v.2.0.0 and those attachments worked.

I just want to clarify:

  * You're sending using Zend_Mail from a local server that is *NOT*
    Exchange
  * Client servers receiving the email *are* using Exchange

Is this correct?

If so, can you provide the full mail pieces with attachments as sent
both by Zend_Mail and either PEAR::Mail or PHPMailer? I would need to
see the full mail, including all mail headers, as it is sent. This can
be done by either creating a transport that simply captures and logs the
mail, or by sending to yourself and posting the received mail somewhere
I can look at it.

Also, please indicate which Zend_Mail transport you are using to send,
the OS you're on, and any options you are using to configure the
Zend_Mail and/or transport objects prior to sending (encoding, character
set, etc.)

Basically, I want to analyze the differences and determine what Exchange
may not be liking about the mails Zend_Mail generates.

I've actually done this already. I have a set of test scripts designed
to send myself an email using a variety of libraries and versions. I
saved the raw source of each email to a file and compared them. It was
greek to me, but maybe you'll have a better idea. I've uploaded them
to http://djcricket.com/emails.tar.gz

Ubuntu 7.10, SMTP transport using Login authentication. The encoding
and character sets are the defaults.

I suspect that Exchange is barfing on the encoding, but I can't be sure
until I look at the samples you've uploaded. I don't have time to do so
today, but will look at them tomorrow morning.

So there might be an issue with the base64 encoding with the ZF code ?
Perhaps its acceptable in most circumstances and M$ is simply being
strict about what it accepts?

Just a guess :)

Hi,

$att = $mail->createAttachment(file_get_contents('example.pdf'));
$att->type = 'application/pdf';
$att->disposition = Zend_Mime::DISPOSITION_ATTACHMENT;
$att->encoding = Zend_Mime::ENCODING_BASE64;
$att->filename = 'example.pdf';
$mail->send();

I tested it with this lines of code and my example.pdf was deliverd without
any problem.
Not reproducable here (Exchange 2007 and SBS 2003)
I saw in the headers that there some filters in. Maybe they have problems
with the mail?

Looks basically the same as my tests. I'm not sure what version of
Exchange the users have, though.

Obviously, if we can't reproduce the problem, it's going to be next to
impossible to fix it. The only things I can think of are asking the
PEAR::Mail_mime / PHPMailer authors if they recall any Exchange
work-arounds, contacting the MS Exchange Team (they have a blog here:
http://msexchangeteam.com/) or finding/creating a VMWare images with
different versions of Exchange and using that to do testing.

We had this problem with one customer running Exchange server v6.5. After some research we noted that the  lines in a base64 encoded block were 2 characters longer when sending an email with ZF than with i.e. Thunderbird.

We changed the value of LINELENGTH on line 41 in Zend/Mime.php to 72 instead of 74. Since then our customer receives attachments alright.

We had a simmilar problem when sending HTML emails with embedded images with
Zend_Mail. Our customer uses Exchange (don't know the version) and Outlook
2003. The image attachments where always corrupted when viewed with Outlook
and Exchange, while other mailclients did not have a problem. Changing the
line length to 72 characters as described by David solved the problem and the
emails are now shown correct. This does not occur while using Outlook without
Exchange.

I'll create a bug report in JIRA and see if we can't get something
done about this. Thanks for your feedback!
