Sending email with iphone and imap backend seems impossible

[JorisHansMeijer]

Describe the issue When sending a email with the iphone I get a error. The logs show that the recipients can't be found. My guess is that the information for the email that needs to be send is completely missing. Sending emails is possible when I hack the code and add recipients by hand.

To Reproduce Steps to reproduce the behavior:

1. Use imap backend
2. Try to send email

Hi @JorisHansMeijer,

From the warnings above it looks like there might have been a problem with the headers and the character encoding in the mime message. This may be affecting how it is parsing the recipients, I don't believe sendmail will accept an email without recipients.

A couple of questions: Was this a forwarded email or a new email entered on the iPhone? What Language do you have set on your phone? What Language was the email in if it is different from you phone's language?

And then a few more questions just to cover the config, in your imap config.php: What is IMAP_SMTP_METHOD set to? What is $imap_smtp_params set to?

Cheers, Mat

Hi,

Thanks for the quick response. Here some answers; It was a new email. I tried both reply and new but both have the same issue, The language I have set is dutch, I just typed some random characters (the repsly message was based on a dutch email),

I don't believe I get to the part where it has a correct message to send, but my settings are: define('IMAP_SMTP_METHOD', 'sendmail'); $imap_smtp_params = array( 'sendmail_path' => '/sbin/sendmail', 'sendmail_args' => '-i' // 'host' => 'ssl://smtp.strato.de', // 'port' => 465, // 'auth' => true, // 'verify_peer' => false, // 'verify_peer_name' => false, // 'allow_self_signed' => true, // 'username' => '-----------', // 'password' => '-----------' );

I tried both smtp and sendmail. Sendmail from the commandline is working ok).

Just as reference, here a somewhat more longer log:

$imap_smtp_params = array( 'sendmail_path' => '/sbin/sendmail'

Do you mind running which sendmail and checking the path?

I got it fixed. It was fixed by using the .htaccess file like:

<IfModule mod_rewrite.c>
        RewriteEngine On
        RewriteRule .* - [E=HTTP_MS_ASPROTOCOLVERSION:%{HTTP:Ms-Asprotocolversion}]
        RewriteRule .* - [E=HTTP_X_MS_POLICYKEY:%{HTTP:X-Ms-Policykey}]
        RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
</IfModule>

<IfModule mod_expires.c>
        ExpiresActive Off
</IfModule>

<IfModule mod_alias.c>
        Redirect 308 /.well-known/caldav /baikal/dav.php
        Redirect 308 /.well-known/carddav /baikal/dav.php
        RewriteRule Microsoft-Server-ActiveSync /Z-Push-2.7.3/src/index.php [PT,L,QSA]
</IfModule>

Glad you got it to work 😊
