ChatGPT replies; Based on the information you provided, it seems that using LMTP for communication between Dovecot and Postfix on the same box is not recommended. According to Dovecot documentation, you can use LMTP and the Postfix setting “reject_unverified_recipient” for dynamic address verification. It's really nice because Postfix doesn't need to query an external datasource (MySQL, LDAP…)*1. *1 https://doc.dovecot.org/configuration_manual/howto/postfix_dovecot_lmtp/ Does this help you?

ChatGPT needs a tuneup. Dovecot in fact, to my readings, shows that LMTP is preferred in this case. The link is one I followed, far as I can tell correctly, which appears to describe setting up LMTP. Sigh.

Thank you for the verification!
As you probably already know, ChatGPT searches by keywords, combines the hits, and displays the results in human spoken language, but,
I don't think posting ChatGPT results is very helpful. AI seems to be better received where its results have been looked at and interpreted by an expert who can check the results for accuracy. So I'd suggest we keep this list to the output produced by human users as before.
1. arbitrary use of keywords
2. Sentence structure that does not care about logical contradictions
As a natural result, it may show false conclusions without hesitation.
Therefore, we should be careful when using ChatGPT, but since it is a human language, it may mislead people's minds.....
BTW.
I'm installing postfix, but not dovecot. But, I get the same result as yours;
# postconf -a cyrus dovecot # postconf -A cyrus
I wonder why ..... ?
Regards.

I was mildly (?) chastised on the postfix list on that issue. Essentially, working as designed, "postfix does not do client side". Lack of fully understanding postfix, or even having a good working knowledge, appears to be part of my issue. Or I am getting too old for this stuff. joea

joea Below is the description of what postconf -a and postconf -A is about (from https://www.postfix.org/postconf.1.html):
Options: -a List the available SASL plug-in types for the Postfix SMTP server. The plug-in type is selected with the smtpd_sasl_type configuration parameter by specifying one of the names listed below. cyrus This server plug-in is available when Postfix is built with Cyrus SASL support. dovecot This server plug-in uses the Dovecot authentication server, and is available when Postfix is built with any form of SASL support. This feature is available with Postfix 2.3 and later. -A List the available SASL plug-in types for the Postfix SMTP client. The plug-in type is selected with the smtp_sasl_type or lmtp_sasl_type configuration parameters by specifying one of the names listed below. cyrus This client plug-in is available when Postfix is built with Cyrus SASL support. This feature is available with Postfix 2.3 and later. It only lists what is available, so what values smtpd_sasl_type and smtp_sasl_type or lmtp_sasl_type can have and depends on what has been build- in. -- fr.gr. member openSUSE Freek de Kruijf

That is not fully correct... postfix can "send" mail to the submission port of a mail server. And it can identify to a server using a different user/password different for each mail send, based on the "From" address. All of that is "client" behaviour.
Lack of fully understanding postfix, or even having a good working knowledge, appears to be part of my issue. Or I am getting too old for this stuff.
I know some parts about postfix and dovecot, but not a complete vision. For example, as my postfix can not get mail from internet, I don't have postfix "connected" to dovecot. Not fully. (1) What are you trying to do? (1) incoming mail, for example, from another machine in the LAN, simply goes to "/var/spool/mail/". And procmail then can sort mail, in the same directory that dovecot uses. Not something to do in a proper mail server for a bunch of users. -- Cheers / Saludos, Carlos E. R.
