While PHP Sendmail support is enabled on the XtreemHost free hosting service, we have had to implement multiple levels of filtering to ensure messages sent via our services are not spamming or otherwise abusing this privilege.

It can take anywhere from a few minutes to fifteen minutes or more for your outgoing e-mail to be processed in the queue and sent out to the intended mail recipients.

However we do not make any guarantees as to the sending of e-mail which may be caught and deleted by our outgoing filters nor the receipt of the message by the intended recipients due to their filters or e-mail provider spam practices.

Please note that any account engaged in bulk/mass mailing campaigns risk having their free hosting account suspended and access terminated.

If the free mail() functions are not working well for you, you should consider using a remote SMTP server. Free Gmail accounts have access to Google’s SMTP servers, and your scripts *should* be able to connect / use these :

You will need a free Gmail account, and enable SMTP/POP.

Then, in your script set something similar to the below:

Use SMTP server for email: Yes
SMTP server address : ssl://smtp.gmail.com
SMTP server port: 465
Authentication method for SMTP: PLAIN
SMTP username: [your Google or GoogleApps/Gmail email address (e.g. you@yourdomain.tld)]
SMTP password: [your Google password]
