Btw: Should the error message not read "Invalid -r parameter: %s"
instead?<br>
<br>
I think the problem is the different handling in Postfix and
Dovecot: <br>
Postfix seems to automatically strip the quotes out of the
username, at least for SQL lookup (but does the splitting
correctly, which Dovecot 2.3 does NOT).<br>
Dovecot does not strip quotes.<br>
<br>
What is the recommended (i.e. endorsed by its developers) way for
Dovecot to deal with Mail addresses containing Quotation marks?
Strip them out? Keep them? Since they are disabled by default
(auth_username_chars), it seems like stripping, but then the
splitting of local part and domain does not work correctly.<br>
Am I really the first one to play around with this? Does it make
sense to prepare patches for example for fixing the splitting?<br>
<br>
On a side note: Has support for UTF8 in local parts already landed
in Dovecot? I could not find up-to-date information on this topic.<br>
<br>
Kind regards,<br>

Adding " to auth_username_chars would help.

Also, -d is used to provide the username. For -d, you could leave
out the double quotes and provide the full e-mail
address--including the required quotes--to the -r argument.
<br>
<br>
It all depends on what your userdb expects.

Can you check what Postfix is feeding to Dovecot exactly
(i.e.,

whether it is properly escaped)? Maybe wrap dovecot-lda in
some shell

script and see what is passed.

<br>
I have a working setup with Postfix + Dovecot, storing
users in a
<br>
MySQL
<br>
table.
<br>
<br>
I ran into problems setting up and using a mail
address like
<br>
a"@"<a class="moz-txt-link-abbreviated" href="mailto:b@mydomain.tld">b@mydomain.tld</a>, which by RFC should be valid, but
leads to
<br>
problems
<br>
in Dovecot. From my debugging, I can see that on the
lookup, Dovecot
<br>
replaces %n with "a" (quotes added by me) and %d with
<a class="moz-txt-link-rfc2396E" href="mailto:b@mydomain.tld">"b@mydomain.tld"</a>
<br>
(quotes added by me). So the original quotes are gone,
and the
<br>
domain/user split is incorrect.
<br>
<br>
I am not sure of Postfix passes the address without
quotes to
<br>
Dovecot or
<br>
whether Dovecot can not handle quotes correctly, but I
was hoping that
<br>
someone with more insight into Dovecot could help me
out here.

Yeah, Dovecot v2.2 is doing some funky stuff with SMTP
address parsing.
<br>
Dovecot v2.3 should do a better job. I am still not sure
if this can be

fixed well for Dovecot v2.2.
