Comment 12 for bug 1992848

Hello,

I'm also affected by this issue as of about 1/12/23

It repeats for every attempt of delivery via Dovecot. I did an 'apt upgrade' and restart with no resolution. My most recent logs are below. I can't receive email so I'll check back on this issue through the website.

I'm running Jammy on a VPS with Postfix as my MTA and Dovecot as my MDA/LDA. Email has worked for the last 6 months on this VPS and for years using a similar stack. This issue came up only within the last few days. The messages are being marked as deferred to the senders but Postfix is receiving them and deferring because Dovecot dies partway through the delivery process.

Another note, this seems to only affect my primary email address. Other accounts are able to receive email from internal and external servers without issue.
