iPhone can't send messages

[Ferma01]

Hello, we have Plesk 7.5 Reloaded, the executives have Iphones but they can't send messages with 3G network, can receive. With wifi everything work fine.

Any idea for the solution different to update version of Plesk?

Thank you in advance.

I do not think that it is related to Plesk version. There is common sending/receiving mail solution as POP3/IMAP/SMTP protocols. Therefore there are no difference which Plesk version in usage. Seems it is network related issue if it works fine via wifi. Maybe SMTP protocol is firewalled for 3G network?

Thank you for your comments Igor, we have another server with Plesk 8.4 and with that server the iPhone works fine, I can't migrate the domain to that server for applications and users policies. We tested the SMTP port, is open in server with Plesk 7.5

May be another idea can be use to solve the issue.

Any comment will be apreciate.

Regards.

In this case maillog should be deeply investigated. You can submit ticket to support team if you can't investigate it by yourself.

I found we had to open port 587.
