Greetings List,
I'm running from 4 years qmail greatly without many problems, but
today something very very bad happened.
From this morning i can't send any e-mail from port 25 no matter if
it's internal or external address. its not send at all.
I think something is blocking port 25 cause from IMAP i can send e-mail.
Can anyone help me, please? I need to have this port 25 working back.
IMAP does not send email. You can only send email on ports 25 and 587
with a stock Qmailtoaster.
You have something going on - when telnetting to port 25, I do not
receive a welcome banner:
[j...@jake-lapbox ~]$ time telnet mail.digital-instruments.com 25
Trying 79.14.157.43...
Connected to mail.digital-instruments.com.
Escape character is '^]'.
Connection closed by foreign host.
real 0m0.381s
user 0m0.000s
sys 0m0.004s
But without more information it's almost impossible to even guess at
what the problem may be.
What recently changed? Can you show us logs? What do you get when you
telnet to port 25 at the localhost? Is there something in the network
that may be intercepting this traffic?
