...would be valid. Sadly, it does not change the outcome. Even with a pure "@"@mydomain.tld, Dovecot splits it into the empty string user (%n) and @mydomain.tld as the domain part (%d).

Dear all, I have a working setup with Postfix + Dovecot, storing users in a MySQL table. I ran into problems setting up and using a mail address like a"@"b at mydomain.tld, which by RFC should be valid, but leads to problems in Dovecot. From my debugging, I can see that on the lookup, Dovecot replaces %n with "a" (quotes added by me) and %d with "b at mydomain.tld"

Interesting, the documentation and the build-in help of dovecot-lda do not mention -r exists :) case 'r': /* final recipient address */ if (smtp_address_parse_path(ctx.pool, optarg, SMTP_ADDRESS_PARSE_FLAG_ALLOW_LOCALPART | SMTP_ADDRESS_PARSE_FLAG_BRACKETS_OPTIONAL, &final_rcpt_to, &errstr) < 0) { i_fatal_status(EX_USAGE, "Invalid -a parameter: %s",

I upgraded to Dovecot 2.3.0.1 as advised, but it still seems broken. In the Postfix log I now see: Mar? 6 13:49:03 myhost amavis[7165]: (07165-10) K00VtLRHdrYw FWD from <admin at mydomain.tld> -> <"@"@mydomain.tld>, BODY=7BIT 250 2.0.0 from MTA(smtp:[127.0.0.1]:10025): 250 2.0.0 Ok: queued as B8CA22DA1B37 Mar? 6 13:49:03 myhost amavis[7165]: (07165-10) Passed CLEAN

I wrapped the LDA command in a script. I can see that Postfix passes "@@mydomain.tld" as the -d argument, without quotes. I then adapted the script to specifically replace this address with "@"@mydomain.tld, but this results in the following error message by Dovecot: ??? auth: Info: userdb(?): Username character disallowed by auth_username_chars: 0x22 (username:
