If your segemnts are broken or Mailtrain complains about missing 20190726150000_shorten_field_column_names.js, run the following in `server/setup/knex/fixes`:
```NODE_ENV=production node fix-20190726150000_shorten_field_column_names.js```
Unfortunately, the migration 20190726150000_shorten_field_column_names.js corrupted the segments table. There is no automatic fix. If this affected you, you have to either revert the DB or fix the segments manually.
Fix - message sent to a list not associated with a campaign couldn't be shown in archive - to know which message to show even if the list is not at the campaign, we store test messages in table test_messages
- More options how to send test emails.
- Fixed problems with pausing a campaign (#593)
- Started rework of transactional sender of templates (#606), however this contains functionality regression at the moment because it does not interpret templates as HBS. It needs HBS option for templates as described in https://github.com/Mailtrain-org/mailtrain/issues/611#issuecomment-502345227
TODO:
- detect sending errors connected to not able to contact the mailer and pause/retry campaing and queued sending - don't mark the recipients as BOUNCED
- add FAILED campaign state and fall into it if sending to campaign consistently fails (i.e. the error with sending is not temporary)
- if the same happends for queued email, delete the message
In v2, text-based segment rules need a "type" property. As in v1 the value could contain % wildcards, the default type for migrated rules should be 'like' to support them.
