hello all,

Got a problem sending email for a domain. As smtp got segfaut and dies after the response from that domain i believe this is affecting other email that were on the same smtp process.

Some log information is here: http://pastebin.com/2Nqvas9z

We will talk to the domain admin but anyone has a tip to workaround, at least to don't affect other domains ?

Thanks

From Pastebin:
Sep 15 08:58:46 mail postfix/smtp[8234]: 3315A1ED07C8:

Temporariamente recusada, se o problema persistir contacte o seu
fornecedor de servico 451-Se acede a partir de um IP dinamico (ADSL
ou dial-up, por exemplo) por favor configure o envio de e-mail para
utilizar o seu ISP. 451- -- 451-Connection refused temporarily, if
it persists contact your ISP. 451 If your IP is a dynamic one (ADSL
or dial-up, for instance) please reconfigure your outgoing settings to
use your ISP server. (#4.5.13) (in reply to RCPT TO command))

The remote server doesnt like your IP as its on a Dynamic block. So
they are refusing your mail.

See http://www.postfix.org/DEBUG_README.html on how to collect
information with a non-interactive debugger.
