## Symptoms

- * Mail Transfer Agent does not process e-mails (does not relay them to Next-Hop) that were queued prior to installation/upgrade/uninstall of [R77.30 Jumbo Hotfix Accumulator](https://supportcenter.checkpoint.com/supportcenter/portal?eventSubmit_doGoviewsolutiondetails=&solutionid=sk106162).

* Relevant only to Takes 221, 225, 226, 266, 272, and 280 of R77.30 Jumbo Hotfix Accumulator.

## Cause

During installation/upgrade/uninstall of Jumbo Hotfix Accumulator, another Postfix version is installed.

As a result, all e-mails that were left on queue are being stuck in a backup folder "postfix_backup".  
E-mails left in this backup folder can not be relayed by MTA.
