Broken postfix/tlsmgr

Support

Description

monit keeps spamming errors and fixes for postfix, and status monitors are reporting port 25 as non-working.

[web2] postfix 
 alert - failed protocol test [SMTP] at [localhost]:25 [TCP/IP] -- Error receiving data from the mailserver -- Resource temporarily unavailable
[web2] postfix 
 alert - connection succeeded to [localhost]:25 [TCP/IP]

Service appears to be up and working, but I found this in maillog:

Local cache becomes corrupted either from an irregular shutdown during an asynchronous write operation or drive ran out of space at one point.

Makes sense, yeah. This node belly up’d few days ago thanks to MySQL logs :innocent:

I’ve added LMDB support to Postfix builds on edge. This can be rebuilt from the public repo.

To switch these caches over after install, run:

cpcmd scope:set cp.bootstrapper postfix_file_dbtype lmdb
upcp -sb mail/configure-postfix
