Retry rules

Description

Retry rules are a tool used in cases when the ISP server responds that the recipient’s mailbox is temporarily unavailable.

Creating, Editing, and Deleting

To manage retry rules, in the main menu select Settings — MTA — Retry rules.

The opened list displays existing AKMTA retry rules. On the right side of the table are the edit and delete buttons. You can also edit a rule by clicking the identifier or name on the left. To create a new rule, click + Create:

The following parameters are available for each rule:

• Name — the rule name. The more informative it is, the more convenient it is to use in sending scenarios.

• Mode — IP selection for retry:

  • Retry from the same IP of the same node — the same IP address on the same node,

  • Retry from any other IP of the same node — any other IP on the same node,

  • Retry from any other IP of any node — any other IP on any node.

• Number of retries — the number of delivery attempts.

• Time interval (min) — the interval between attempts.

• Type — the type of interval increase between attempts:

  • Fixed (no increase) — fixed interval without increase,

  • Geometric increase delay — geometric interval increase exponentially,

  • Calculated random delay — interval increase by a random value with a modifier.

• Exponent — exponent for interval increase in geometric progression.

• Random modifier — modifier for calculating the random interval increase.

note

The minimum random value for interval increase is the interval itself. The maximum is the interval multiplied by (1 + Random modifier).
