Blackberry unable to setup mail account from specific host.

[Coza]

Hi guys,

I am having a few issues with setting up blackberries with my host provider.

When i try setup the mailbox it gives me an error, username and or password is incorrect, try contact your host.

I have had my host monitor their logs, and they are not picking up any login attempts from a blackberry, they have also white-listed all of blackberry's ip ranges.

I am loathed to contact MTN's help desk.

Does anyone know how i can contact top level Blackberry support in SA ?

I host multiple domains with this host, and multiple accounts across multiple domains cannot be configured, although they were working and i am able to setup accounts on other ( hetzner ) hosts.

Id like to see if blackberry can pickup anything in their proxy logs, as to why this is happening.

Have the host got port 110 open and port 143. I tried using POP3 and it failed. So I tried using IMAP and it failed. Opened both ports, and it registered no issue. Was then able to close the IMAP port, and POP3 still worked. Switch to using IMAP only, as it was my preference. Need to ensure that the firewall rule allowed 110 incoming as destination, and 110 outgoing as source in both cases. Original problem lay in that I didn't have 143 as the source on outgoing.
