Emails not forwarding to Hotmail, Gmail or Yahoo

emailEmail Forwarding Problems

If you are using the free SMTP service provided with your UKC hosting account then sometimes there may be problems with deliverability to the free email providers.

As this is a shared service, performance may be limited by the actions of other users. For example, rogue users could cause a build-up of backlogged mail, and can even cause the server to become temporarily blacklisted.

There is also the possibility that some users may be using the system to spend spam and other malicious email. In this case, other email systems may see this spam and blacklist the server.

This could cause your emails to be delayed or, in the worst case, bounced back.

Ensure your Email / Domain is in your Recipient Safe Senders list

All of the large providers offer a “safe senders” list. You should ensure you ask your clients that use free email addresses as the contact details to ensure your domain is added to their “safe senders” list to ensure deliverability.

See: How we ask our clients to add us to their safe senders list

Use your ISP SMTP Server for maximum deliverability

For best SMTP performance we recommend that you use your ISP SMTP server.

See: Which SMTP server should I use to send email?

UKC email not arriving at your Hotmail address?

If you are using to manage your or emails, do ensure that you have added as a safe sender as follows:

  • Login to your Hotmail account at
  • Settings > Options > Junk Email > Safe Senders
  • enter “”
  • Press the “+” button.
  • Then click Save

Hotmail will now deliver emails from UKC to your address without delay.

That’s all there is to it!

How to fix: (98)Address already in use: make_sock: could not bind to address

sshApache Error: (98) Address already in use

Occasionally your VPS or dedicated server will just not play ball.

Whenever Apache gives up the ghost it usually a case of restarting the service and within seconds your sites are back online, as if nothing happened. Great!

# service httpd restart

Most of the time, this resolves the issue. But, on occasion, apache simply doesn’t want to play. The most common issue we hear about is the Address already in use issue, which looks something like this

# service httpd restart
Stopping httpd:                                            [FAILED]
Starting httpd: (98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address
no listening sockets available, shutting down
Unable to open logs

How to resolve this apache issue

Unless apache is restarting at the time you are trying to restart manually then what we have here is a locked process. Thankfully the resolution is quite simple. We just need to find the locked process, kill it then restart apache as usual.

Let’s find the locked process id

# netstat -ltnp | grep ':80'

This will return something like this

tcp  0  0 :::80  :::* LISTEN      3826/sudo

Now we have identified the PID as 3826, we just need to kill it

# kill -9 3826

With a little luck, a simple apache start will now get everything working

# service httpd start

Starting httpd: [  OK  ]

If the problem persists then review the apache error log to locate the issue:

# tail -500 /var/log/httpd/error_log

How to: Create DNS SRV Records

sshCreating SRV Records

Some services, such as Microsoft 365, will require SRV records to be created.

SRV records are constructed as follows:

_service._protocolName IN SRV priority weight portNO

The following parameters are needed to fully construct SRV records:

  • Service
  • Protocol
  • Port
  • Weight
  • Priority
  • Name
  • Target
  • TTL

A sample SRV record could look like this:

_https._tcp IN SRV 10 10 443

Microsoft 365 SRV records can look like this:

_sip._tls IN SRV 100 1 443
_sipfederationtis._tcp IN SRV 100 1 5061

Query SRC record with DIG with as such:

# dig srv

;; ANSWER SECTION: 38400 IN SRV 10 10 443

Setting up SRV records can be complicated. Simply contact the Helpdesk with the parameter list and our support staff will construct the SRV record on your behalf.
