Severity: normal


I tried to use sender_dependent_relayhost_maps this way:

main.cf:
sender_dependent_relayhost_maps = hash:/etc/postfix/sendermap

sendermap:
jan@voelkers.org        smtp:[mx.voelkers.org]

but got this error:
Jun  7 11:43:41 mailout0 postfix/smtp[25599]: fatal: unknown service: [mx.voelkers.org]/tcp
Jun  7 11:43:42 mailout0 postfix/qmgr[25597]: warning: transport smtp failure -- see a previous warning/fatal/panic logfile record for the problem description

With this sendermap file it works:
jan@voelkers.org        [mx.voelkers.org]

also this:
jan@voelkers.org        [mx.voelkers.org]:25

Sincerely,

Jan
