Postfix+SASL: No worthy mechs found

Hi folks,

since one of my recent updates to my self-built image, I have trouble sending mails via Postfix's relay mechanism.
When postfix tries to relay one of my mails, it fails setting up SASL:

Tue Jan 14 15:55:07 2020 mail.warn postfix/smtp[1868]: warning: SASL authentication failure: No worthy mechs found
Tue Jan 14 15:55:07 2020 postfix/smtp[1869]: 194231642F: to=<XXX@YYY>,[JJ.KK.LL.MM]:25, delay=147662, delays=147662/0.07/
0.25/0, dsn=4.7.0, status=deferred (SASL authentication failed; cannot authenticate to server[JJ.KK.LL.MM]: no mechanism available)

I encountered this error after shrinking my OpenWRT config. I removed libgnutls, libmbedtls and Samba4.
For testing, I re-added them. It didn't work.
Version: r11966-97940f8766

  • postfix with TLS, SASL and CDB
  • SASL

Does anyone know where to look at?
Has anyone encountered a similar problem?


The issue has been fixed by commit d6cb60f.
