Postfix can't start

[futadict]

Hi!

I have a problem, after a power failure my server can't start mta, the postfix says this:

Feb 8 10:50:17 mail postfix/smtpd[21738]: fatal: host/service 127.0.0.1/None not found: Servname not supported for ai_socktype
Feb 8 10:50:18 mail postfix/master[12946]: warning: process /opt/zimbra/postfix/libexec/smtpd pid 21738 exit status 1
Feb 8 10:50:18 mail postfix/master[12946]: warning: /opt/zimbra/postfix/libexec/smtpd: bad command startup -- throttling

I've been looking but I don't find anything like this, anyone knows how can I fix it?

This is my version: Release 7.1.4_GA_2555.F11_64_20120105094338 F11_64 FOSS edition.


Thanks for any help
