Squirrelmail webmail not sending

[bmarshallbri]

Hi All,

I like all of you have been having the same problem. Here's how I fixed it.

# Block outgoing SMTP except for root, exim and mailman (forces scripts/users
# to use the exim/sendmail binary instead of sockets access). This replaces the
# protection as WHM > Tweak Settings > SMTP Tweaks. This will block hosting
# clients from using your server as an SMTP relay

SMTP_BLOCK = 1

# If SMTP_BLOCK is enabled but you want to allow local connections to port 25
# on the server (e.g. for web scripts) then enable this option too

SMTP_ALLOWLOCAL = 1

I originally had SMTP_ALLOWLOCAL = 0 and SMTP_BLOCK set to 1. The notes in the config make mention of local script access.

Worked for me with SquirrelMail's conf set to useSendmail = false;

Good luck!

If you have:

SMTP_BLOCK = 1

then

SMTP_ALLOWLOCAL should also be set to "1"

This worked for me as well.

I found this problem withc csf firewall. And this is an interesting post in the forum of csf

Could someone clarify if this is the same issue ?

Customer sends email via horde or squirrel but receives the following error...

Authentication failed
Server replied: 535 Incorrect authentication data


I have SMTP tweak disabled in WHM and

SMTP_BLOCK = 1
SMTP_ALLOWLOCAL = 1 In CSF

Also Editing The

I managed to fix the problem without editing any config files. Thanx to this post:

If you receive: SquirrelMail Not Found

Do This:

rm /usr/local/cpanel/base/3rdparty/squirrelmail/ -rf

then

/scripts/upcp --force

If you get Operation Not Permitted when trying to rm squirrelmail, do this:

chattr -ia /usr/local/cpanel/base/3rdparty/squirrelmail/config/config.php

then do rm /usr/local/cpanel/base/3rdparty/squirrelmail/ -rf



If Getting The 110 Can't Open SMTP Error:

Do this:

Edit the following file, and change useSendmail to true, instead of false:

/usr/local/cpanel/base/3rdparty/squirrelmail/config/config.php

Save this, and close it, but you must do the following so that cpanel doesn't change useSendmail back to false:

chattr +ai /usr/local/cpanel/base/3rdparty/squirrelmail/config/config.php

Its reeally quite simple folks, adjust your firewall config. It is much faster and cleaner than many of these patches I have seen. I have not seen one person with this issue that did not have their CSF misconfigured.

chattr'ing files ensures that you will never get another cPanel update in this area. Is that what you really want?

Flushing the IP tables fixed the problem for me.

Interestingly, other than Squirrelmail not working, one or two users could not authenticate and send mail through the server with their Thunderbird client, while others could.

strange issue.

service iptables stop
iptables -F
service iptables start

fixed any issues instantly.

[cpaneldave]

Flushing IP Tables is simply removing all your rules. I wouldn't recommend this if you are using iptables to block unwanted traffic. Instead, I'd take a look at any rules you have related to the ports you've configured for mail traffic and adjust those rules. Also, you should note that just doing iptables -F isn't actually changing your configuration and that upon reboot, your issue will return.

[jimmy1987]

The simpelest and only possible solution for the Can't open stream error is the CSF SMTP Block setting to 0 or setting the allowlocal to 1 too.

That is the only solution! Don't go screwing around with your configs or chatt'ring things blonging to cPanel.
