To make it work the current way, is simple.

I would love for it though, to lookup and see if an mailbox exists with the delim first, then if it doesn't lookup just the username part.

Hi,

It would be nice if the recipient_delimiter configuration option supported multiple recipient delimiters as Postfix now does. e.g. now if I set: recipient_delimiter = +- in Postfix, then test-extension@sample.com and test+extension@sample.com are both recognized. But if I set: recipient_delimiter = +- in Dovecot, neither of the above are recognized and instead test+-extension@sample.com is valid.

Well, presently this feature isn't that important to me, but I imagine it could be a source of confusion for people who are migrating from say qmail to postfix (as I am doing) and notice Postfix's cool ability to support both types of delimiters and assume Dovecot will as well (as I did).

Thanks, Andrew Ray

Well, to answer my own wishlist, this isn't by no means complete, as I only use lmtp, so I didn't bother to patch lda, but logins already worked good the way it was, so just needed lmtp to match with delim first, then try again without it. --- dovecot-2.2.10/src/lmtp/commands.c 2013-08-21 16:30:17.000000000 -0400 +++ dovecot-2.2.10/src/lmtp/commands.c 2014-01-28 20:18:12.303577376 -0500 @@ -387,7 +387,7 @@ return; domain = strchr(address, '@'); - p = strstr(address, client->unexpanded_lda_set->recipient_delimiter); + p = strpbrk(address, client->unexpanded_lda_set->recipient_delimiter); if (p != NULL && (domain == NULL || p < domain)) { /* user+detail@domain */ *username_r = t_strdup_until(*username_r, p); @@ -536,7 +536,7 @@ memset(&input, 0, sizeof(input)); input.module = input.service = "lmtp"; - input.username = username; + input.username = address; input.local_ip = client->local_ip; input.remote_ip = client->remote_ip; input.local_port = client->local_port; @@ -545,6 +545,16 @@ ret = mail_storage_service_lookup(storage_service, &input, &rcpt.service_user, &error); + if (ret<=0 && strlen(detail)>0) { + input.username = username; + ret = mail_storage_service_lookup(storage_service, &input, + &rcpt.service_user, &error); + } else if(ret>0) { + username=t_strdup(address); + if(strlen(detail)>0) + detail = ""; + } + if (ret < 0) { prefix = t_strdup_printf(ERRSTR_TEMP_USERDB_FAIL_PREFIX, username);
