Special character in email ID

New to postfix please bare with us. :)

We like to accept special characters in email id so surrounding the email names with "", but still these emails are sent to fallback maildir.

Followed this man page --> http://www.postfix.org/aliases.5.html
The name is a local address (no domain part). Use double quotes when the name contains any special characters such
as whitespace, `#', `:', or `@'. The name is folded to lowercase, in order to make database lookups case insensi- tive.

E.g., $first...@box.com, &tes...@mail.com, #te...@ju.com

Wrapped them as "$firstemail"@box.com, "&testem"@mail.com, "#test"@ju.com as well "$first...@box.com" - but no use.

Hmm...any thing else need to take care of ???

You missed this valuable part of this line "(no domain part)"

Aliases allows "$firstemail" or "&testem" or "#test". You MUST NOT
include the domain part.

As always, aliases(5) maps are only used for those users that are
delivered by the local(8) delivery agent.

Brian, Thanks for the reply.

We have put quotes surrounded the mail name part only excluded the domain and made sure that main.cf has

resolve_dequoted_address as yes

We receive email from external sources and postfix forwards to our local mail store, here is the value of

"virtual_alias_maps" in main.cf

virtual_alias_maps = regexp:/etc/postfix.myd/my_domain_aliases.regexp, hash:/etc/postfix.myd/virtual_users, hash:/etc/postfix.myd/virtual_dlists, hash:/etc/postfix.myd/dropboxes, regexp:/etc/postfix.myd/dropboxes.subdomains.regexp, regexp:/etc/postfix.myd/unrewrite.regexp

Sample virtual_users fragment

"#critica...@mydomain.com" ms23/007/000/002/106/@mail.dir

"#critica...@mydomain.another.com" ms23/007/000/002/106/@mail.dir

postmap creates virtual_users.db file using virtual_users and uses for lookup.

My perception is during the lookup it is not able to resolve the email to corresponding maildir, hence routing to fallback maildir rather than bouncing it back.(we don't want it to get bounce that part is fine).

Please let me know for more info.

"#critica...@mydomain.another.com" ms23/007/000/002/106/@mail.dir

postmap creates virtual_users.db file using virtual_users and uses for lookup.

There is no reference to virtual_users in the above virtual_alias_maps.

I think you are confusing virtual_alias_maps and virtual_mailbox_maps; this is not uncommon.

For a virtual address to be delivered to a virtual mailbox, the domain in question must be present in virtual_mailbox_domains AND the address must resolve to a mailbox in virtual_mailbox_maps.

Use

postmap -q "query" maptype:/map/location

to validate your maps.

Thanks a lot, mean while i will validate using postmap command,i assume the bold text is the reference ??

Yes, it is; it was buried beneath the irrelevance.

As I said before, virtual_alias_maps does not concern virtual *mailboxes*.

postconf -n gave the following

virtual_mailbox_maps = regexp:/etc/postfix/v_m_box.regexp

Content is

if /@mail\.dir$/
/^(.*)@mail\.dir$/ $1
endif

i guess this may confirm the mailbox a valid one.

Any other info do i need to look into?

TIA

I am not sure what the question is.

The observed behaviour corresponds with the configuration; if that is not what you intended, we will need more specific details on what you did intend.

Thank Jeroen.

I have executed the postmap command against the virtual_users, when i issue

postmap -q test...@mydomain.com /etc/postfix/virtual_users it gives me the corresponding maildir value but when i say

postmap -q #critica...@mydomain.com /etc/postfix/virtual_users --- syntax wrong

postmap -q "#critica...@mydomain.com" /etc/postfix/virtual_users --- no result

postmap -q ""#critica...@mydomain.com"" /etc/postfix/virtual_users --- no result

Now the question boils down to how to give escape characters in this case to query the map??

Here is my sample virtual_users fragment

"#critica...@mydomain.com" ms23/007/000/002/106/@mail.dir

"#critica...@mydomain.another.com" ms23/007/000/002/106/@mail.dir

test...@mydomain.com ms11/007/000/002/108/@mail.dir

No, it does not - since this is a virtual ALIAS map, and not a mailbox map.

but when i say

postmap -q #critica...@mydomain.com /etc/postfix/virtual_users --- syntax wrong

You'd need to quote the address localpart, as per the RFC.

postmap -q "#critica...@mydomain.com" /etc/postfix/virtual_users --- no result

Meaning no match was found.

postmap -q ""#critica...@mydomain.com"" /etc/postfix/virtual_users --- no result

Meaning no match was found.

Now the question boils down to how to give escape characters in this case to query the map??

The first example - double qoutes - will work fine.

I am still unclear what it is you want to achieve with all this; it is difficult to advise you to do anything until you explain this.

I apologize i have not included what are all combinations i have tried....none worked, all i'm trying to do is

if the key has '#' in it how you query using postmap.

[root@myserv~]# postmap -q "#criticalemail1"@mydomain.com /etc/postfix/virtual_users

[root@myserv~]# postmap -q "##criticalemail1"@mydomain.com /etc/postfix/virtual_users
