The function returns false if the message fails validation or is rejected by qmail-queue, and returns true on success. If you are using the sendmail app from an exim package or something you don't really need to change the normal parameters PHP gives it -t -i as other posts described.
I just added "-f myemail example. One thing that got me stuck for a few hours was trying to figure out why the return-path was set as the user user running php and not what I was setting it with the -f option then I later found at that in order to forcefully set the return-path the user account running the command must be in exim's trusted users configuration! When I sent mail manually this was not an issue.
Unlike Sendmail, qmail requires locally-injected messages to use Unix newlines LF only. This is a common problem with PHP scripts. So now, I can go back to sending emails with text AND html components :. I haven't fully tested it like with microtime with long mails. I send html message as 7-bit, so I didn't try yet with html.
If you have good html practise, you don't really need to encode html as quote-printable as it only uses 7-bit chars. Simply setting From: email address. So to subscribe to mylist example. I've noticed that on some versions of PHP occasionally mail returns the empty string for success, rather than true or false. The empty string evaluates to false. Note, that single line should not contain more than 78 character, but is not allowed to contain more than characters.
The possible consequences are: Over 78 - clients are allowed to display the message in a "harder to read" way. Over - clients and servers are allowed to drop the message or cause any buffer-limit error. The ideal workaround is to use the smtp functions which servers allow because of its better audit trail. Alternatively call the mail function several times. I've just spent about four hours trying to work out what I was doing wrong!!
Just a comment on some of the examples, and as a note for those who may be unaware. When sending MIME email make sure you follow the documentation with the "70" characters per line Outlook seemed to be a little finicky with me to have carriage returns in the headers. Hope that helped. If you're sending a large attachment, you may encounter overflow problem. AFAIK, two common limits could be responsible. Active 4 years, 3 months ago. Viewed 5k times.
