Retry Timing

Sets how many times this server retries sending failed messages, and the interval in minutes between these retries. Unless explicitly set, the default retry times are "30,720," meaning the first retry occurs 30 minutes after the first attempt, the second retry after 12 hours, and that a total of 2 retries is attempted. Retry intervals should be separated by commas:

30,60,90

Each interval measures the time, in minutes, between the previous try and the next try. The smallest acceptable retry interval is six minutes and the largest acceptable retry interval is 1440 minutes (24 hours). Retry intervals which are not within the acceptable range is ignored. For example, if you have one retry of three minutes, no retries are attempted.

For example, if you want to establish a retry schedule of 30 minutes, two hours, eight hours, and 24 hours, you would enter the following values:

30,120,480,1440

For most lists, two retries are more than enough. If you are running Aurea List Manager for the first time with lists that have many bad email addresses, you may want to have only one retry to make delivery quicker. Once members with bad email addresses have been put on hold and purged (based on your settings in Utilities: List Settings: Automatic Maintenance: Error Mail), your mailing speeds increases and you may reset the retry timing to less aggressive settings.

Fallback HELO text

Specifies the string Aurea List Manager uses in the HELO portion of the SMTP transaction if Aurea List Manager is unable to construct a HELO text from site or DNS information. Normally, Aurea List Manager uses the Internet host name for a site to determine the HELO text. If it is unable to do so, Aurea List Manager performs a reverse lookup on the first TCP/IP address of the machine it is running on to determine the HELO string. To have Aurea List Manager use a different HELO string, specify it here.

Example:

lists.example.com

Changing the HELO text is extremely useful if you are behind a firewall and machines on the Internet cannot resolve the hostname your machine uses.

Configure Relay Hosts

Relay all outbound mail through this mail host rather than doing regular direct delivery.

Lyris strongly recommends that you not use a relay host, because Aurea List Manager has been optimized to send mail directly to the Internet. Using a relay host may delay mail delivery, and result in inaccurate delivery reports. Some bounced mail may also be returned to the relay host instead of Aurea List Manager, preventing Aurea List Manager from handling error mail correctly.

However, some environments need outbound mail to be relayed through a specific host. For instance, your organization might employ a TCP/IP firewall that prevents Aurea List Manager from directly delivering mail. In such a case, each application behind the firewall must use a relay host to communicate with the outside.

If the specified relay host(s) listed are unavailable, Aurea List Manager considers the failed delivery attempts as transient failures and attempts retries according to the retry timing specified above.
