I use sendmail to send, relay messages to internet. On Kerio mail server messages are received OK, but Lotus Domino mail server not accept sender - syntax error, because address from is: name@net1.agro.
Address ending with dot.
Thank You for help

Re: Sendmail - from address ending dot

Re: Sendmail - from address ending dot

Hi,
I not end email with dot. We have program, which send mail automatically.
I test send mail from command line:
**********
mail aaa@agrostroj.cz
From: aaa@net1.agro
Subject: test
To: aaa@agrostroj.cz
.

***********
and I receive mail from "aaa@net1.agro." with "." dot on end address.
Thank You

Re: Sendmail - from address ending dot

Email standards will not process an email to an address ending with a dot.

Dots are transition characters for domain names not termination characters. The Domino server is behaving correctly.

If a dot is being appended check the processing mail server or the mail client.

Re: Sendmail - from address ending dot

Just a hunch, but it looks like the mail client is attempting to validate the top level domain. I don't think that agro is a valid tld, where cz is used for the Czech Republic. Are you sure that the full address is name@net1.agro and not something like name@net1.agro.cz?

Re: Sendmail - from address ending dot

can you check your /etc/resolv.conf if you are using a corect domain.

I have seen a simmular problem and it was fixed by putting a

[host-ip] [hostname] [hostname]. [hostname].[domain] in the hostfile.

please alsow post you sendmail.cf

Re: Sendmail - from address ending dot

Hello all,
I remove # from two line in sendmail.cf file:
In Ruleset 4 - Final Output Post-rewriting:
# strip trailing dot off possibly canonical name
R$* < @ $+ . > $* $1 < @ $2 > $3
In Ruleset 0 - Parse Address: SParse1:
R< $+ . > $* $: < $1 > $2 strip trailing dot

and received mail have this format:
Return-Path:
without dot on end address. It is OK and mail is forwardet to Lotus Domino mail server OK.
Thank You for help
