Topic: SME Server cannot receive email

[loejf]

Hi.
Could anyone please help.
Since yesterday my SME suddenly cannot receive emails, no problems with sending.
I have checked for any changes in DNS, Firewall etc. Everything is ok.
I have therefore today upgraded from version 7.4 to version 7.5.1, but it did not resolve the problem.
I cannot find any errormessages.
Best regards
Loejf

Do you have a fixed IP address? Did your provider perhaps start blocking port 25?

Did you already look at the relevant logfiles (see http://wiki.contribs.org/Log_Files#E-mail_logfiles )? Are you seeing incoming connections in there or not?

Hi.
25 is open through my isp, has been checked.

The only suspicious thing I can see is:
Permissions on spool_dir /var/spool/qpsmtpd/ are not 0700

So checking it:
drwxr-s---   2 qpsmtpd clamav 36864 Jun  3  2010 qpsmtpd

Is this OK ??

Hmmm.
After comparing 2 SME, it seems more to be something about the qpsmtpd plugin peers, that is the problem:
Do anyone know if this howto is outdated on version 7.5.1, or is it worth trying ?

Hi.
Problem solved.
After much work, and finally made a port scanning, port 25 was still filtered from the ISP (

LOL, so you learned to always check your provider when they state that they have checked. Good to hear you got things solved.
