Mailbox Problems – Sending Mail
Before going any deeper into sending issues it should be noted that ‘most’ sending problems are caused by not having all the settings correctly configured. Mail can work, or appear to work, with just some of the settings correct which can be confusing when you then start to get problems.
Common configuration issues:
1. Using port 25 for outgoing mail may produce intermittent problems.
None of our mail client setup help recommends using port 25. If you are using port 25 for mailboxes with us then you should change this to port 225. A large number of ISPs route port 25 traffic through their own SMTP servers which can cause intermittent results if the mail account is not with them.
2. Your mail program is not authenticating for sending with the mailserver.
Our mailservers require authentication prior to accepting mail for sending. Normally if you have ‘read’ mail within the last 15 minutes then this automatically authenticates you for sending but after that you would not be authenticated unless you explicitly set this option within your mail client. This option is normally a tick box which is titled ‘My Server Requires Authentication’. Once ticked you hightlight the option that says ‘use same settings as incoming’ or authenticate in clear text with your User name (email address) and mailbox password.
