$sql = "Long line: 123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890123456789012345678901234568901234567890";
mail($address, $subject, $sql);

In this case the mail function isn't working properly. When the string line ist too long, unexpected characters are inserted (this is "!/n")

hello,
got this bug on
linux debian 2.2.17 potato
php 4.0.1pl2

more info about the number of characters.
990 characters is fine,
991 is bad, and "!\n" appears on the 990 position.

good luck :-)

Works fine for me... what mail program do you use?

I'ld suggest to try with a newer PHP version anyway.

I'm a web developer and I've been experiencing a very similar problem. Infact, it almost identical to the problem reported in Bug #31496 (I would have added my comment there, but I couldn't do so because it was listed as "Bogus"). 

But in my case, the problem is INTERMITTENT, where the garbage exclamation point character ! will appear in different places in a given message. (If it occurs at all). Sometimes the messages will be prefectly fine. Other times, I'll get an exclamation point somewhere in the body of the message. And other times, there will be several exclamation points in a given message.

I strongly suspected the Zend Optimizer causing these bugs, as it tries to look ahead, it may be invoking the mail/sendmail program inproperly or before the message has finished being fully formed.

Please respond with any opinions on that theory. Thanks

Steve

I am using a standard Ubuntu 6.06 Dapper Drake installation (PHP 5.1.2, Postfix ,and Apache 2.0.55 (unbutu)) and am having similar problems. 

extra characters are are very consistent, and all emails with too-long lines are getting that "!/n" characters put in.

I ran into this same problem.  I was able to fix it by adding in newline characters.  From what I can determine, it is caused by too many characters on one line.

In my case, I was sending an HTML e-mail and I didn't bother with newlines because I was using HTML formatting.

By adding newline characters (I added them where I would if I were creating a nicely formated HTML webpage) I was able to avoid this bug.

I hope this helps you guys too.

I have this problem with PHP 5.2.5.
Seems that when the message exceeds a certain length it adds strange characters (</p> in the message, splits a word with a space character, ...)

I had several links in my HTML email. The effect described above could be resolved by adding the target attribute to the link. 

Note that exactly the same HTML would be correct and would bring no error within browsers. This effect only applies to HTML emails sent with the PHP mail() function.

<a href="url">text</a> 
in some emails causes the characters <p> to be inserted at the end of paragraphs or spaces to be inserted within words (splitting them up) in the subsequent html

<a href="url" target="_self">text</a> (also target="_blank" or whatever)
does not bring this effect

I was having a similar problem sending the Content-Type: text/html through the php mail() function.  Extra spaces were being inserted almost randomly.  If I added text, the space would move down the number of spaces I added.

I was pulling the HTML from a database, and everything was inserted on a single line.  Inserting newlines corrected the problem.

This is a standard limit of sendmail/smtp. See here for details: http://safari.oreilly.com/1565928393/ch20-77125

Solution is to use base64-encoding
 [2012-02-29 05:02 UTC] brendan at brendanenglish dot com
Try using 'wordwrap' when sending the message, this should break up the email and 
fix the issue:

@mail($to, $subject, wordwrap($message), $headers);

Thanks! :)

Similar case was with me, when i was printing email on console, it was not showing any spacial characters, but in outlook mail is was displaying unwanted characters like (!).
after using wordwrap() to mail body.

thanks for hint :)

The text is too long, you can add a "\n" after the <tr>,similar to the function of wordwrap
