PHPmail issues

[bananaspider]

Hi, I'm having a weird email issue. Whether I use PHPmail or SMTP, no emails are received from my corporate email address when a ticket is submitted and/or replying to their tickets within Hesk. If using gmail address, etc, they always receive these emails. I've checked the spam folders, etc but nothing. My host states their is no filtering going on and PHPmail and/or smtp should be working fine (which it is if the recipient is other than my corporate email). What else can I check here? Now, I've even set up a test email smtp account on my outlook email to test send and I can receive those emails via my corporate email address. So, this sort of tells me that it is within Hesk where the issue resides. Any clues anyone has for me? Otherwise I may have to look elsewhere and test their phpmail to see if it is some kind of filter within my corporate email system that is denying form emails for some reason. Don't know why this would be the case. Anyway, Thanks!

The exact same code is used when sending to any email address so how does this lead you to believe the issue is within Hesk?

Hesk doesn't filter any outgoing emails, it delivers them to either PHP mail or your SMTP server and then it's out of it's hands; it's ultimately up to the SMTP server to deliver them.

What exactly is happening I don't know. To figure that out one would need access to your server and help desk to test and probably also to smtp logs on the server.

Thanks for response. Any suggestions? I don't even know if putting the system in debug mode will give any information as emails are getting out just not being received by my Exchange account.

Are you having problems with email notifications to staff or customers only or both?

[bananaspider]

Only emails from one organization which uses Exchange email. When they submit a ticket, no confirmation is received and when update a ticket no email is received by them. Any other emails to individuals goes through fine, for example, users who use gmail. Do you think somewhere in the company's filtering is blocking these emails? Thanks.

Also, I should mention, I have also this Exchange email and when I change my admin account email to this, I get no emails.

You would need to check server email logs to confirm mails are being sent (that an error doesn't happen during SMTP exchange for example) and if they are being accepted by the exchange server, they are definitely being blocked there.

will check that out through my host. Thanks!
