[Koha-bugs] [Bug 43340] Koha does not gracefully handle SMTP 421 responses

https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=43340 --- Comment #2 from Kyle M Hall (khall) <kyle@bywatersolutions.com> --- I believe I was mistaken about the most basic issue. After more research I remembered we are using Email::Sender::Transport::SMTP::Persistent ( Bug 33964 ) so unless there is a bug in that lib, it's unlikely to be the problem. Be it that or not, the solution is the same. We need to implement an initial and exponential backoff anytime Koha gets a 421 response ( https://mailtester.com/blog/automate-retry-logic-421-4-7-0-try-again-later/ ). -- You are receiving this mail because: You are watching all bug changes.
