package postfix 3.1.0-3ubuntu0.4 failed to install/upgrade: subprocess installed post-installation script returned error exit status 75

[Taras Holubets]

Hello, I have received the tupical error message:

Oct 18 15:03:54 Taras-X52N postfix/smtp[10311]: 41159A01E4: to=<from_field_account@Taras-X52N>, relay=mail.network.lviv.ua[195.211.84.8]:25, delay=0.48, delays=0.04/0/0.19/0.24, dsn=5.0.0, status=bounced (host mail.network.lviv.ua[195.211.84.8] said: 550 relay not permitted (in reply to RCPT TO command))

What do you tell me about the section to=<from_field_account@Taras-X52N> in other word does this problem reply to inccorect postfix configuration or this is a bug during resolving unknown host name Taras-X52N via local /etc/reslov.conf cofiguration?

Regards, Taras

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Since it seems likely to me that this is a local configuration problem, rather than a bug in Ubuntu, I'm marking this bug as Incomplete.

If indeed this is a local configuration problem, you can find pointers to get help for this sort of problem here: http://www.ubuntu.com/support/community

Or if you believe that this is really a bug, then you may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem, explain why you believe this is a bug in Ubuntu rather than a problem specific to your system, and then change the bug status back to New.
