Controling the retry intervals in the SMTP outgoing queue?
The outgoing queue for sent e-mails from the Icewarp Mail Server is controlled by:
The first attempt to deliver is always just after the message enters the queue.
The default retry intervals are as follows:
After the 8th retry, the same retry interval will be used until the Undeliverable after threshold is reached (Set in Mail tab > General > Delivery tab).
If you wish to set your own retry intervals you should modify intervals in the Mail tab > General > Delivery tab --> Retry Intervals dialog.
The default undeliverable Warning after can also be changed in Mail Service -> SMTP Service -> Delivery tab.
Note that for certain "immediate" errors these retry values are ignored and Icewarp retries after 6 hours. If this retry fails a message is sent to the sender informing him of the problem but Icewarp keeps retrying for 4 days. If the message still cannot be sent, the sender is informed.
